Soli-State Radio Module GKP-2781 1.General GKP-2781 is sloid-state radio module of compact weather radar. It is composed with STALO, Signal Processor, and Transmitter/Receiver Module. The source oscillation signal is generated in Signal Processor. Transmitter/Receiver up-convert the source oscillation to the transmission frequency by mixing it with the local signals generated in STALO. 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. 1st Local Signal STALO DCN-DC922-102IR 2nd Local Signal Transmitter /Receiver Transmission CMN-827 Signal To Antenna Signal Source Oscillation Signal Processor CMJ-569 Block Diagram of transmission 1/2
