Abstract:

This paper introduces the design idea and the implement method of a kind of Xband fourchannel T/R module.Such advanced technologies as LTCC, MCM and new silicon aluminum material design are adopted in the module, in view of some difficulties such as higher working frequency, broader bandwidth, complex function, more channels, more bare chips, strict weight demand and so on.The miniaturized fourchannel T/R module is developed successfully with low noise figure, light weight, and complete functions. The operation bandwidth can be up to 2 GHz, the transmitting power can reach up to 41 dBm,the transmitting efficiency is as high as 32%, the noise figure is 2.5~2.8 dB, the phase shift precision (RMS value) is 2°, and the whole weigh is only 96 g. The module has been in the stage of mass production.
