RF performance is maintained. • Identify the bands that need to be supported, particularly when both the MC5720 and MC8755/8765 will be installed in the same platform. In this case, you may want to develop separate antennas for maximum performance. -
Page 17: Interference And Sensitivity
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 (MC5720) If your host device is not designed to use the MC5720’s diversity antenna, terminate the interface with a no‐connect. Interference and sensitivity... -
