Abstract :
We report on a 60 GHz-band InP HEMT resistive mixer that can be operated with very low LO-power. The mixer is fabricated using Coplanar Waveguide (CPW) techniques to reduce production costs. A narrow source-to-drain space and a short length gate (0.15 μm) are employed in order to reduce the LO-power requirement. The minimum conversion loss of 8.4 dB is achieved at a 55 GHz RF frequency with LO power of -2 dBm. This low LO-power is comparable with the best data ever reported for millimeter-wave passive mixers. In addition, the mixer has an excellent IF output linearity that indicates capability to provide good intermodulation performance
