[0002] The microwave transmitter and receiver (T / R Transmitter and Receiver, abbreviated as T / R) component is one of the most important components of the active phased array radar system. The volume, weight, electrical performance, etc. of the T / R component directly determine the various technical indicators of the active phased array radar signal reception and transmission. In the prior art, the packaging method of the active phased array radar T / R transceiver component generally adopts the MCM (multi-chip module) structural design and assembly method for system integration. That is, various active or passive devices are mounted or wire-bonded on the surface of the LTCC substrate to form a radio frequency transceiver system. This MCM packaging mode has promoted the miniaturization of the T / R component.
