A novel 16-31GHz quadruple subharmonic monolithic passive mixer with a chip dimension of 0.82 × 0.7mm2 is designed and fabricated using the 0.15μm GaAs pHEMT process. The novel configuration of the quadruple subharmonic mixer consists of a lumped frequency diplexer and a low-pass filter utilizing a pair of anti-parallel Schottky barrier diode to achieve quadruple subharmonic mixing mechanism. The lumped frequency diplexer formed with a low-pass network and a high-pass network is used to reduce the chip dimension while operating at low frequency band and to improve the isolation between the RF and LO ports with a broadband operation. The low-pass filter supports an IF frequency range from DC to 2.5GHz. From the measured results, the mixer exhibits a 12.5-16.5dB conversion loss, a LO-to-RF isolation better than 15dB, a 50-59dB high 4LO-to-RF isolation over 16-31GHz RF bandwidth, and an input 1dB compression power of 2dBm.
