RSSI output from the TP_RSSI_A2D test point. It uses a dynamically adaptive threshold to control dual PIN diode D510, to switch between the internal antennas. The received RF signal enters an image rejection helical filter (FL510). The filter FL510 in conjunction with a discrete filter post LNA attenuates the 1st LO frequency from reaching the antenna ports. The RF signal is then down-converted with
