摘要

This article presents a circuit topology for a wideband subharmonic image rejectionmixer. The mixer circuit is realized by employing two identicalsubharmonic mixers based on Schottky antiparallel diode pair, a wideband 90°differential phase shifter and a band pass filter without involving bonding wires,high impedance or tightly coupled arms. To demonstrate the topology, a mixerwith 1 GHz as the fixed intermediate frequency is fabricated for 6 to 10 GHz ofRF frequency. The lower side band is considered as the undesired band. Measurementresults exhibit a minimum conversion loss of 7.87 dB and a maximumimage rejection ratio of 41 dB at a local oscillator drive level of 9 dBm. Measured1 dB compression point is 3 dBm. There is no requirement of DC bias.
