3. RF Specifications
The EM9190 includes Four MHF4 RF connectors for use with host-supplied antennas, and eight
MHF7S connectors for use with up to four mmWave antenna modules (2 connectors per antenna
module):
Figure 3-1 Module Connectors Include Image with Spacing Info
Sub-6G/GNSS connectors:
Main: Primary Tx/PRx path for 3G/4G/5G (except for n41)
Auxiliary: Diversity Rx (except for n41) and GNSS L1
MIMO1: MIMO1 Rx Path and n41 TRx
MIMO2: MIMO2 Rx Path and n41 DRx and GNSS L5
mmWave connectors:
Eight connectors —Up to four mmWave antenna modules (QTM525 or QTM527), two
connectors as a pair (H/V) for each. The EM9190 module does not have integrated antennas.
Refer to Table 3-1 for each pair of coaxial connections. For low-power usage, if not all 4
QTM525 modules are equipped, integration sequence from QTM0 to QTM3 is recommended,
leave unused connectors NC (Contact Sierra Wireless as the RFC has to be updated to reflect
the number of QTMs). Note that for high-power usage, it’s not recommended to leave any
QTM527 NC as it will violate 3GPP EIRP compliance for PC1.

AirPrime EM9190 Hardware Integration Guide RF Specifications
3.1. RF Connections
When attaching antennas to the module:
Sub-6G /GNSS connectors:
Use RF plug connectors that are compatible with the following RF receptacle connectors:
I-PEX (20449-001E (MHF4)).
Match coaxial connections between the module and the antenna to 50Ω.
Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna
cabling is 0.5 dB.
mmWave connectors:
Use RF plug connectors that are compatible with the following RF receptacle connectors:
I-PEX (20956-001E-01 (MHF7S)).
To ensure best thermal performance, use the ground hole (if possible) to attach (ground) the
device to a metal chassis.
Note: If antenna connection is shorted or open, the modem will not sustain permanent damage.
3.1.1. Shielding
The module is fully shielded to protect against EMI and must not be removed.
3.2. Sub-6G Antennas and Cabling
When selecting the Sub-6G antennas and cables, it is critical to RF performance to match antenna
gain and cable loss.
Note: There is no explicit list of antennas required in the application. The PWB-6-60-RSMAP Wide Band
4G/5G Terminal Paddle Antenna has been verified as a reference. For detailed electrical
performance criteria, see Antenna Specification.
Choosing the Correct Sub-6G Antenna and Cabling
When matching antennas and cabling:
The antenna (and associated circuitry) should have a nominal impedance of 50Ωwith a return
loss of better than 10 dB across each frequency band of operation.
The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test
results.
Designing Custom Sub-6G Antennas
Consider the following points when designing custom antennas:
A skilled RF engineer should do the development to ensure that the RF performance is
maintained.
If multiple modules will be installed on the same platform, you may want to develop separate
antennas for maximum performance.
Determining the Sub-6G Antenna’s Location
When deciding where to put the antennas:
Antenna location may affect RF performance. Although the module is shielded to prevent
interference in most applications, the placement of the antenna is still very important —if the
host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the
module’s performance.
Connecting cables between the module and the antenna must have 50Ωimpedance. If the
impedance of the module is mismatched, RF performance is reduced significantly.

41113915 Rev 0.3 June 17, 2020 11
AirPrime EM9190 Hardware Integration Guide RF Specifications
Antenna cables should be routed, if possible, away from noise sources (switching power
supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be
coupled into the RF cable and into the antenna. See Interference from Other Wireless Devices.
Disabling the Auxiliary (Diversity) Antenna
Certification testing of a device with an integrated EM9190 may require the module’s main and
diversity antennas to be tested separately.
To facilitate this testing, receive diversity can be enabled/disabled using AT commands:
!RXDEN —used to enable/disable diversity for single-cell call (no carrier aggregation).
!LTERXCONTROL —used to enable/disable paths (in carrier aggregation scenarios) after a call
is set up.
Note: LTE networks expect modules to have more than one antenna enabled for proper operation.
Therefore, customers must not commercially deploy their systems with the diversity antenna
disabled.
A diversity antenna is used to improve connection quality and reliability through redundancy.
Because two antennas may experience different interference effects (signal distortion, delay, etc.),
when one antenna receives a degraded signal, the other may not be similarly affected.
3.3. Ground Connection
When connecting the module to system ground:
Prevent noise leakage by establishing a very good ground connection to the module through the
host connector.
Connect to system ground using the ground hole shown in Figure 3-1.
Minimize ground noise leakage into the RF. Depending on the host board design, noise could
potentially be coupled to the module from the host board. This is mainly an issue for host designs
that have signals traveling along the length of the module, or circuitry operating at both ends of
the module interconnects.
3.4. Interference and Sensitivity
Several interference sources can affect the module’s RF performance (RF desense). Common
sources include power supply noise and device-generated RF.
RF desense can be addressed through a combination of mitigation techniques (Methods to Mitigate
Decreased Rx Performance) and radiated sensitivity measurement (Radiated Sensitivity
Measurement).
Note: The EM9190 is based on ZIF (Zero Intermediate Frequency) technologies. When performing EMC
(Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from
the module to consider.
3.4.1. Interference from Other Wireless Devices
Wireless devices operating inside the host device can cause interference that affects the module.
To determine the most suitable locations for antennas on your host device, evaluate each wireless
device’s radio system, considering the following:
Any harmonics, sub-harmonics, or cross-products of signals generated by wireless devices that
fall in the module’s Rx range may cause spurious response, resulting in decreased Rx
performance.

41113915 Rev 0.3 June 17, 2020 12
AirPrime EM9190 Hardware Integration Guide RF Specifications
The Tx power and corresponding broadband noise of other wireless devices may overload or
increase the noise floor of the module’s receiver, resulting in Rx desense.
The severity of this interference depends on the closeness of the other antennas to the module’s
antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your
host device’s design.
3.4.2. Host-generated RF Interference
All electronic computing devices generate RF interference that can negatively affect the receive
sensitivity of the module.
Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx
performance. Components that are most likely to cause this include:
Microprocessor and memory
Display panel and display drivers
Switching-mode power supplies
3.4.3. Device-generated RF Interference
The module can cause interference with other devices. Wireless devices such as AirPrime embedded
modules transmit in bursts (pulse transients) for set durations (RF burst frequencies). Hearing aids
and speakers convert these burst frequencies into audible frequencies, resulting in audible noise.
3.4.4. Methods to Mitigate Decreased Rx Performance
It is important to investigate sources of localized interference early in the design cycle. To reduce the
effect of device-generated RF on Rx performance:
Put the antenna as far as possible from sources of interference. The drawback is that the module
may be less convenient to use.
Shield the host device. The module itself is well shielded to avoid external interference. However,
the antenna cannot be shielded for obvious reasons. In most instances, it is necessary to employ
shielding on the components of the host device (such as the main processor and parallel bus)
that have the highest RF emissions.
Filter out unwanted high-order harmonic energy by using discrete filtering on low frequency lines.
Form shielding layers around high-speed clock traces by using multi-layer PCBs.
Route antenna cables away from noise sources.
3.4.5. Radiated Spurious Emissions (RSE)
When designing an antenna for use with AirPrime embedded modules, the host device with an
AirPrime embedded module must satisfy any applicable standards/local regulatory bodies for radiated
spurious emission (RSE) for receive-only mode and for transmit mode (transmitter is operating).
Note that antenna impedance affects radiated emissions, which must be compared against the
conducted 50Ωemissions baseline. (AirPrime embedded modules meet the 50Ωconducted emissions
requirement.)
3.5. Radiated Sensitivity Measurement
A wireless host device contains many noise sources that contribute to a reduction in Rx performance.

EM9190 hardware include IF and BB part for mmWave support, it has to work with Qualcomm QTM525 or QTM527 chipset
41113915 Rev 0.3 June 17, 2020 13
AirPrime EM9190 Hardware Integration Guide RF Specifications
To determine the extent of any receiver performance desensitization due to self-generated noise in
the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by
Sierra Wireless or you can use your own OTA test chamber for in-house testing.
3.5.1. Sierra Wireless’ Sensitivity Testing and
Desensitization Investigation
Although AirPrime embedded modules are designed to meet network operator requirements for
receiver performance, they are still susceptible to various performance inhibitors.
As part of the Engineering Services package, Sierra Wireless offers modem OTA sensitivity testing
and desensitization (desense) investigation.
Note: Sierra Wireless has the capability to measure TIS (Total Isotropic Sensitivity) and TRP (Total
Radiated Power) according to CTIA's published test procedure.
3.5.2. Sensitivity vs. Frequency
Sensitivity definitions for supported RATs:
UMTS bands —sensitivity is defined as the input power level in dBm that produces a BER (Bit
Error Rate) of 0.1%. Sensitivity should be measured at all UMTS frequencies across each band.
LTE bands —sensitivity is defined as the RF level at which throughput is 95% of maximum.
5G NR Sub-6G bands —sensitivity is defined as RF level at which throughput is 95% of
maximum.
3.6. Supported Frequencies
The EM9190 supports data operation on 5G NR, 4G LTE and 3G networks over the bands described
in Table 3-2.

3.7. Antenna Specification
This appendix describes recommended electrical performance criteria for Sub-6G, GNSS, and
mmWave antennas used with AirPrime embedded modules.
The performance specifications described in this section are valid while antennas are mounted in the
host device with antenna feed cables routed in their final application configuration.
Note: Antennas should be designed before the industrial design is finished to make sure that the best
antennas can be developed.

Sierra Wireless recommends using
antenna efficiency as the primary
parameter for evaluating the antenna
system.
Peak gain is not a good indication of
antenna performance when integrated
with a host device (the antenna does not
provide omni-directional gain patterns).
Peak gain can be affected by antenna
size, location, design type, etc. —the
antenna gain patterns remain fixed
unless one or more of these parameters
change.

See Important Compliance Information for
the United States and Canada.
Isolation
>10dB for all antennas at all bands
frequency range.
>20dB for Ant1 and Ant4 at B41

If antennas can be moved, test all
positions for both antennas.
Make sure all other wireless devices
(Bluetooth or WLAN antennas, etc.) are
turned OFF to avoid interference.
Power Handling
>1W
Measure power endurance over 4 hours
(estimated talk time) using a 1 W CW
signal —set the CW test signal
frequency to the middle of each
supporting Tx band.
Visually inspect device to ensure there is
no damage to the antenna structure and
matching components.
VSWR/TIS/TRP measurements taken
before and after this test must show
similar results.
1. These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits.
The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50Ωsystem. With antenna
designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be
tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels
of emissions. Tuning may include antenna pattern changes, phase/delay adjustment, passive component matching.
Examples of the application test limits would be included in FCC Part 22, Part 24 and Part 27, test case 4.2.2 for WCDMA
(ETSI EN 301 908-1), where applicable.
