W波段收发前端设计研究

Research on Design of Transceiver Front-end of W-band

以21.12 GHz为本振信号、93.12~94.136 GHz为射频信号,采用"倍频+超外差发射机"和"超外差接收机"设计了毫米波无线通信系统收发前端模块组件,其中上变频模块尺寸为20 mm×19 mm×82 mm,实现了小型化,用完成的收发前端组件与已有的频率源组成完整的相参性测试系统,并对频率源的相参性进行了验证.

This paper adopts multiplier ＋ superheterodyne transmitter,,and superheterodyne receiver,, to design a millimeter wave wireless communication system front-end module component by using 21.12 GHz as local oscillator and 93.12-94.136 GHz as radio-frequency signal. The size of the up-conversion module is 20 mm × 19 mm × 82 mm,through which miniaturization is realized. We form a complete test system to test the coherence by combining the current frequency source with the transceiver front-end modules, and verify the coherence of the frequency source.
