Abstract

The invention discloses a four-channel microwave T/R module. The four-channel microwave T/R module has a common cavity structure consisting of the same four independent T/R channels, wherein all the components are MMICs (Monolithic Microwave Integrated Circuits) being integrally fabricated on the same multilayer circuit board. The four-channel microwave T/R module is characterized in that a microwave device is a multifunctional MMIC bare chip integrated with a phase shifter, an attenuator, a working state switch, an amplitude limiting low noise amplifier and a driver; and the multi-layer circuit board is an HTCC multi-layer circuit board. The four-channel microwave T/R module has the advantages of compact structure, small size, high wiring density, low material cost, high mechanical strength, stable chemical performance, corrosion resistance, high temperature resistance, multiple channels, high performance, high reliability, high integration degree, light weight, low power consumptionand high heat dissipation characteristic, and can monitor the transmission and reception phases of each T/R channel. Compared with an existing microwave T/R module, the four-channel microwave T/R module has the advantages that the weight and volume of the microwave T/R module are reduced by 30 percent or more under the same function and index conditions. The four-channel microwave T/R module can be widely used in airborne, shipborne, spaceborne phased array radar and communication fields.

Description

technical field [0001] The invention relates to a radar phased array antenna, in particular to a four-channel microwave T / R assembly. Background technique [0002] The microwave transmitter and receiver (Transmitter and Receiver, abbreviated as T / R) component is one of the most important components of the active phased array radar system, one end of which is connected to the antenna, and the other end is connected to the intermediate frequency processing unit to form a wireless transmission With the receiving system, the function is to amplify, phase shift and attenuate the signal. Its performance directly affects the detection effect of the entire active phased array radar system. The rapid development of modern active phased array The volume and weight of T / R components in airborne, shipborne, and spaceborne radars are subject to stricter restrictions. At present, the functions and performances of microwave T / R components at home and abroad are basically completed by sep...
