Design of Ka-Band Active Imaging Wideband Transceiver Module

Based on the background of millimeter wave active imaging, a Ka-band wideband transceiver module was developed. The design process fully considers the system indexes and cost factors. Through experimental tests, in the 32-37GHz operating frequency range, the output power reaches 22dBm, the power flatness is within 1dB, the spurious suppression is greater than - 70dBc, and the phase noise is degraded by 12dB. The transceiver system has a wide range of applications in millimeter-wave systems by the unique low cost design.
