11. Overview
1.1. A43364A
Anaren AIR for Wi-Fi A43364x modules are based on the CYW43364 chipset from Cypress. They are surface-
mounted 2.4GHz radio frequency (RF) transceivers incorporating Wi-Fi technology that conforms to the WLAN
IEEE 802.11b/g/n. The CYW43364 chipset integrates an ARM® Cortex®-M3 processor and on-chip memory
for complete WLAN subsystem functionality, minimizing the need to wake up the applications processor for
standard WLAN functions. All control lines are provided at the module level for full control of the operation. Also
incorporated in the modules are a STMicroelectronics STM32F412 ARM Cortex-M4-based microcontroller, two
26MHz crystals (one for the radio and the other for the microcontroller), the required RF matching and ltering
for regulatory compliance, and ltering for noise reduction and sensitivity.
The A43364x modules have received regulatory approvals for full modular devices in the United States (FCC),
Canada (IC), and Europe (ETSI). The modular approval allows the end user to place either an A43364A or an
A43364C with an approved antenna inside a nished product without having to perform costly regulatory testing
for an intentional RF radiator. Section 2.3. Approved Usage has information on the requirements for the end
user/integrator to fulll in order to use the modules without intentional radiator regulatory testing.
The module is available in two variations: A43364A and A43364C. The A43364A has an integral antenna, and
the A43364C uses an external antenna through a U.FL connector. Each module measures 11mm x 19mm x
2.5mm, and are footprint compatible with each other.
The A43364A module has an integral antenna, providing high efciency and near-omni-directional radiation
pattern. This approach offers the lowest system cost when the application allows collocation of the radio and
antenna. See Figure 6 and Figure 7 for more information on antenna location and enclosure considerations.
1.2. A43364C
The A43364C module has a compact antenna connector that allows for locating the antenna away from the
module due to form or function, or in order to exit a metal enclosure. See Table 1 for a list of approved antennas.

1.4. Theory of Operation
The A43364x module operates in the global 2.4 GHz ISM/SRD frequency band. It can be used to implement a
variety of networks, including point-to-point, point-to-multi-point, and peer-to-peer.
Figure 1 below shows the functionality of A43364x module. Both modules operate in a similar manner with
the exception of the antenna—the A43364A communicates through a built-in antenna, and the A43364C
communicates through an external antenna attached to a U.FL antenna port.

1. Overview
The description of the functional blocks shown in Figure 1 is given as follows:
• Antenna: The antenna couples energy between the air and the module. The integral antenna and the external
monopole antenna—both centered at 2441.75 MHz—provide a near-omni-directional antenna pattern with
high efciency, such that the application will work in any direction. The end radiation pattern of the antenna
depends on the ground plane, enclosure, and installation environment.
• Matching and Filtering: The matching provides the correct loading of the transmit amplier to achieve the
highest output power and the correct loading for the receive LNA to achieve the best sensitivity. Filtering
removes spurious signals to comply with regulatory requirements, provides reduced susceptibility to power
supply and digital noise, and lters out RF and high-frequency noise from the communication data and control
link.
• TX/RX Chain: The TX/RX chain handles transmitting and receiving of the communication data based on the
radio register settings. It involves the coordination of several blocks, including the modulator, demodulator,
AGC control, frequency synthesizer, and frame control.
• Crystal: The crystal oscillator provides the necessary clock reference for the entire module operation. The
A43364x modules use two 26 MHz crystals: one for the radio and one for the microcontroller.
• Power Management: Power management ensures a stable supply for the internal functions, as well as providing
means for a low-power sleep mode.

A helpful document that can be a starting point in understanding the use of short range devices (SRD) in Europe
is the European Radio Communications Committee (ERC) Recommendation 70-03 E , which is downloadable
from the European Radio Communications Ofce (ERO) at www.ero.dk.
The end user is responsible for ensuring compliance with harmonized frequencies and labeling requirements for
each country the end device is marketed and sold. For more information, see:
• Radio And Telecommunications Terminal Equipment (R&TTE): ec.europa.eu/enterprise/rtte/index_en.htm
• European Conference of Postal and Telecommunications Administrations (CEPT): www.cept.org/
• European Telecommunications Standards Institute (ETSI): www.etsi.org/
• European Radio Communications Ofce (ERO): www.ero.dk/
2.2. Potential Interference Sources
A43364x modules operate in the unlicensed ISM band, in which there are many other applications (e.g. WLAN,
Classic Bluetooth, Bluetooth Low Energy, and microwave ovens). This can cause interference that may, in
certain conditions, prohibit radio communication.
Some of the most common interferences are listed below.
2.2.1. WLAN
Wireless local area networks (WLAN) are divided into a number of overlapping channels. Figure 3 below shows
the channels used by WLAN; for the U.S. and Canada, only channels 1-13 may be used. Predominantly, channels
1, 6, and 11 are used to achieve non-overlapping channels. The user is therefore encouraged to select unused
WLAN channels in their respective environment.
Figure 3: WLAN Channels

92. Approvals and Usage
2.2.2. Classic Bluetooth®
Classic Bluetooth divides the 2.402-2.480 GHz band into 79 channels, each of which is 1MHz wide. However, since
Bluetooth changes channels rapidly (up to 1600 times a second), it is unlikely to cause continuous interference in
a specic channel and can be overcome by implementing a simple acknowledge/retransmit functionality.
2.2.3. Microwave Ovens
A typical microwave oven uses a self-oscillating magnetron with a duty cycle below 50%, because the tube is
completely off for half of every alternating current (AC) mains cycle (8.33 ms in 60 Hz countries and 10 ms in 50
Hz countries). The frequency of the microwave oven changes cyclically within each AC mains synchronized on
period, and is generally not predictable.
The user is encouraged to have packet transmission durations less than half the AC mains period and implement
an acknowledge/retransmit method.
2.2.4. Other Interference
Systems similar to the user’s system may also exist within range and may also be a source of interference. Some
typical applications to consider include the following:
• Alarm systems: These typically use low duty cycles and are therefore easy to avoid using acknowledge/
retransmit methods
• Car alarms (internal motion sensors)
• Video surveillance: These are operated on a xed channel (determined during installation) and can be avoided
by using clear channel assessment. It may be useful to change the channel used by the video surveillance
equipment.
2.3. Approved Usage
A43364x modules have been approved for use in the U.S., Canada, and Europe. The user is encouraged to use
minimum power required to establish a link, thus minimizing interference.
Changes or modications to the module and/or operation outside the limits are prohibited and could void the
user’s authority to operate the modules.
2.3.1. U.S. and Canada
Within the U.S. and Canada, A43364x modules have been approved for use as digitally-modulated transmitters,
for which they conform to the bandwidth (a minimum of 500 kHz 6-dB bandwidth for U.S., a maximum bandwidth
of 0.5% of the carrier frequency for Canada), power spectral density (max of 8 dBm / 3 kHz), total output power
(max of 1W including the antenna gain) and spurious radiation (harmonics and others including the restricted
bands) requirements.
Table 2 shows approved frequencies of operations with the corresponding maximum output power values. These
modules must be operated at or below the indicated power levels. Using the modules with higher power levels
are prohibited, and will void the user’s authority to operate the modules under current FCC/IC certication.

application PCB layout for both. Below the pinout is shown:
Figure 4: A43364x Module Pinout (viewed from top side)
Where applicable:
• NC = “No Connection”
Pin is not connected internally.
• DNC = “Do Not Connect”
Pin reserved for internal use; ensure mating footprint
pads are isolated.
• GND = “Ground”
Connect the maximum number possible (minimum
one for proper operation).
• TGND = “Thermal Ground”
Connect to ground plane on PCB for optimal heat
conduction out of the module.

3.6. Recommended Layout
3.6.1. Module Usage Guidelines
The recommended PCB layout is shown in the gures above.
• If the design is using the on-module PCB antenna, the antenna’s “No GND Plane” area labeled above needs
to be kept clear of copper on all layers to ensure good RF performance.
• If the design is using an external antenna via the U.FL connector, it is okay to overlap the antenna area with
copper. However, the design with an external antenna needs to meet appropriate regulatory requirements
depending on the target geography, such as FCC, IC, MIC/TELEC, etc. Contact Anaren for additional
information.
Figure 5: Recommended PCB Footprint
NOTE: The “No GND” area is optional for A43364C modules. It may still be provided for compatibility with the
internal antenna version (A43364A).
In addition to the above guidelines, note the following suggestions:
• Place external bypass capacitors as close as possible to the module pins.
• To achieve better communication quality, keep metallic objects away from the antenna (either the on-module
chip antenna or an external antenna) as much as possible.
