Abstract:

The Ku RF signal is changed to 1.25～1.75 GHz IF signal by down-converter and divided into 26-channel signal by splitter.Each channel signal is followed by filter and power detector.When the RF frequency falls into a channel filter,the channel detector outputs detector voltage which is compared with neighboring channel detector voltage and absolute voltage,then outputs the results to FPGA.FPGA generates frequency codes,simultaneous signals and ready indication by estimating and coding.

Key words: channelized;frequency measurement;receiver
