A 7. 5W microwave T/R module is designed in this thesis. The thesis mainly research on scheme, high power amplifier and structure of gold wire interlinkage. The module is realized through the regime of phased array. The transmitter of T/R module consists of phase shifter, attenuator, high power amplifier, and the receiver is composed by low noise amplifier, phase shifter, attenuator. The switch between the receive and the transmit is realized through SPDTs. We choose a multi-function chip to achieve both of...
