Research on W-band Up-conversion module

Up-conversion module is the core of transmitter, which plays a critical role in millimeter wave communication, radar, guidance and electronic warfare. This paper introduces the design and measurement of a W-band up-conversion module. W-band LO signal is obtained by frequency multiplying, then through up-conversion method, an X-band signal is converted to W-band. By fabricating, assembling and measuring, the experimental results indicate that the module´s output RF power is more than 5 dBm at the RF frequency of 91~95 GHz, power flatness is less than 3 dB and output linear dynamic range is more than 50 dB.
