V/UHF IQ digital Transceiver

The Transceiver operates in V/UHF frequencies is mainly used in Handheld and Manpack Radios. The transceiver can produce a power output of 1 W and can have a medium range of communication link. All processing, modulations and demodulations are done at IQ level with better BER performance. Appropriate filtering of analog signal is done and fed to ADCs and DACs. All the submodules are controlled through TTL lines. Synthesizer programming is done through SPI.
