Main Features 
The integrated design uses software radio technology, has a small size, and realizes data interaction through network interface, asynchronous RS422, synchronous RS422, and other interfaces, completing telemetry data PCM encoding, carrier modulation, transmission, and remote control signal reception, demodulation, and other functions. This transceiver baseband board is a general-purpose broadband wireless communication core board platform. After the external signal conditioning and collection board, power amplifier, LNA, and other expansion boards, it can quickly integrate and design multi-functional aircraft measurement and control terminals, realizing telemetry, remote control, and video transmission functions of the aircraft.
