A Novel Low Loss W-Band Transmit and Receive Module with MEMS Prcocessing

This paper proposed a novel waveguide probe structure in the w-band transmit and receive front -end which is fabricated by MEMS package technology. The waveguide probe offers the 0.3dB low-loss in the W-band and integrated the MEMS package module with the traditional RF component. With the waveguide probe transition, the transmitter designed in this paper working frequency 92–95 GHz, emission gain 28.5 dB, output power 28.5 dBm. The gain of the receiver is 40 dB in the operating frequency range of 92–95 GHz, noise figure 5.6 dB. The research and development of MEMS package products will push transmit and receive module to realize higher frequency W-band, higher integration, compact module size and lower system cost.
