Use Hirose U.FL connectors (3 mm x 3 mm, low profile; model U.FL #CL331-0471-0-10) to attach antennas to connection points on the module.
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 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. 12 Proprietary and Confidential - Contents subject to change 4118013
If both UMTS and CDMA modules will be installed in the same platform, you may want to develop separate antennas for maximum performance. RF Specifications Determining the Antennas 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 modules 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 Use the AT command !RXDEN=0 to disable receive diversity or !RXDEN=1 to enable receive diversity. 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. 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 modules RF performance
(RF desense). Common sources include power supply noise and device-
generated RF. Rev 1 Sep.15 Proprietary and Confidential - Contents subject to change 13 Hardware Integration Guide RF desense can be addressed through a combination of mitigation techniques
(Methods to Mitigate Decreased Rx Performance on page 15) and radiated sensitivity measurement (Radiated Sensitivity Measurement on page 15). Note: The MC7455 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 devices radio system, considering the following:
Any harmonics, sub-harmonics, or cross-products of signals generated by wireless devices that fall in the modules 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 modules receiver, resulting in Rx desense.
The severity of this interference depends on the closeness of the other antennas to the modules antenna. To determine suitable locations for each wireless devices antenna, thoroughly evaluate your host devices design. Host-generated RF Interference All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module. Display panel and display drivers Switching-mode power supplies 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
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. 14 Proprietary and Confidential - Contents subject to change 4118013 RF Specifications
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.) 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.
