Exciter Receiver Processor Unit (ERPU)
Exciter Receiver Processor Unit (ERPU) is indigenously developed by CoreEL and LRDE. CoreEL has developed all the sub-modules in house, except VPX & HCD.
ERPU is a Multi-Processor system, which is designed to meet high processing speeds and bandwidth. It receives the four RF channels from the RF down converter (RFDC) of AAAU of AESA Radar. Inside ERP, these four channels of frequencies 1630MHz for narrow band (NB) mode and 1640MHz for wideband (WB) mode will be down converted to 70MHz for NB mode and 200MHz for WB mode.
