Transceiver subsystem, as the front of radar system, affects the standard of the whole radar system directly and must be the one of the key components of the radar. The transceiver subsystem described in this paper is designed for distributed array radar, which has a 4*16 array surface consisted by sixty four transmit-receive channels. It achieves a 10W’s transmitting power as well as an 80dB’s gain for each channel. What’s more, for both transmitting and received signal, the amplitude and phase could be controlled digitally.
