Hardware Integration Guide
RF Connections
When attaching antennas to the module:
• Use IPEX (20449-001E (MHF4))to attach antennas to connection
points on the module.
Note: To disconnect the antenna, make sure you use the IPEX MHF4 connector removal
tool to prevent damage to the module or coaxial cable assembly.
• Match coaxial connections between the module and the antenna to 50 .
• Minimize RF cable losses to the antenna; the recommended maximum
cable loss for antenna cabling is 0.5 dB.
• To ensure best thermal performance, mounting holes must be used to
attach (ground) the device to the main PCB ground or a metal chassis.
Note: If the antenna connection is shorted or open, the modem will not sustain permanent
damage.
Shielding
The module is fully shielded to protect against EMI and the shield must not
be removed.
Antenna and Cabling
When selecting the antenna and cable, it is critical to RF performance to
match antenna gain and cable loss.
Choosing the Correct Antenna and Cabling
When matching antennas and cabling:
• The antenna (and associated circuitry) should have a nominal impedance
of 50  with a recommended 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 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.

Rev 1 July 12, 2022 12
RF Specifications
Determining the 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
perfor- mance.
• Connecting cables between the module and the antenna must have 50 
impedance. If the impedance of the module is mismatched, RF
performance is reduced significantly.
• 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.
Disabling the Diversity Antenna
Certification testing of a device with an integrated EM7590 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:
• AT!RXDEN— Used to enable/disable diversity for single-cell call (no
carrier aggregation).
• AT!LTERXCONTROL— Used to enable/disable paths (in carrier
aggregation scenarios) after a call is set up.
Important: 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.
Note: A diversity antenna is used to improve connection quality and reliability through
redundancy. Because two antennas may experience difference interference effects (signal
distortion, delay, etc.), when one antenna receives a degraded signal, the other may not be
similarly affected.

Rev 1 July 12, 2022 13
Hardware Integration Guide
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 two mounting holes at the top of
the module.
• 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.
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 on page 13) and radiated
sensitivity measurement (Radiated Sensitivity Measurement on page 14).
Note: The EM7590 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.
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.
• 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.
Host-generated RF Interference
All electronic computing devices generate RF interference that can negatively
affect the receive sensitivity of the module.

Rev 1 July 12, 2022 14
RF Specifications
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
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.
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.
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 50-ohm emissions baseline. (AirPrime
embedded modules meet the 50-ohm conducted emissions requirement.)

Rev 1 July 12, 2022 15
Hardware Integration Guide
Radiated Sensitivity Measurement
A wireless host device contains many noise sources that contribute to a
reduction in Rx performance.
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.
