Receive Switch Matrix
The SWRxxx series receive switch matrix is designed for use in relay cell local multipoint distribution service wireless systems where two receivers are used. The unit provides monitoring of the receiver's critical operating parameters and provides microprocessor-controlled automatic switching to a hot-standby receive path. The SWR monitors receive PLL lock voltages, LDC PLL lock voltages and RF receive levels.
