We have developed a 15/60 GHz one-stage MMIC frequency quadrupler using a 0.25-/spl mu/m AlGaAs/GaAs HEMT. The HEMT was characterized by our empirical large-signal model, in which charge conservation and dispersion are taken into consideration. We included this model in a commercially-available harmonic balance circuit simulator, and designed the one-stage quadrupler. The fabricated MMIC quadrupler has a conversion gain of -5 dBm with -5 dBm of output power for a 0 dBm input signal.
