    RF Specifications • If both UMTS and CDMA modules will be installed in the same platform, you may want to develop separate antennas for maximum performance. 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 —...

  • Page 14: Interference From Other Wireless Devices

    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.

  • Page 15: Methods To Mitigate Decreased 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.
