C-Band Weather Radar Radio Module GKP-2794
1/2
1.General
GKP-2794 is sloid-state radio module of weather radar. It is composed with STALO, DSP Unit,
TRX Unit Module, and PA Unit. The source oscillation signal is generated in Signal Processor. TRX Unit
up-convert the source oscillation to the transmission frequency by mixing it with the local signals
generated by STALO, and amplifies it at the PA Unit.
Since this is solid-state type, it does not require either pre-heat or tune-up. Also, it is possible
to keep stable transmission and low power consumption for longer period of time.
Details of the components are shown in the next page.
