Description
TRM stands for Tx /Rx Module, The module consists of 04 TX/RX Channel, TRM controller, Health Monitoring and Power supply card. The TRM will have single Tx / Rx input port and 4 output ports to be connected directly to antenna. Each Tx / Rx Channel will have independently controlled separate phase shifters and attenuators.
