Overview


ELD-PES02064 DTRM - RF front end control unit

RF front end control unit for S-band TRM is custom form factor card which is part of 150W TR module. This board is used in interfacing with the antenna array in RADAR system. RF front end control unit for S-band TRM is capable of RF transmission and reception at S-band frequencies with signal conditioning with filtering and amplification over the signal chain.

The system’s control mechanism has to meet the timing requirement of the RADAR. The phase shifters need to be configured with the frequency of incoming TRP. The system monitors the temperature and DC voltages continuously and reports it periodically.

ELDAAS developed test jig and GUI interface to control and monitor the TRM status and configuration of phase,TRP etc.
