Abstract :
In this contribution, an active high harmonic suppression x8 frequency multiplier using depletion-mode mHEMT devices and its design procedure are presented. The realized circuit exhibits 3 dB conversion gain in the 86.4 - 91.2 GHz output frequency range, with 6 dBm output power. An harmonic suppression higher than 32 dBc has been achieved. The whole chip current consumption is 125 mA, occupying an area of 2.05 × 3.45 mm2.
