  • Abstract
    Summary form only given, as follows. The Class B to Class J continuum of modes, exploited here, offers Class B levels of efficiency over a continuum of impedance matching conditions, making wider bandwidth designs more feasible compared to resonant harmonically tuned approaches. Circuits were designed to systematically use the continuum of modes for the first time at X-band. A 0.5 W MMIC fabricated using a GaAs pHEMT process yields above 65% drain efficiency over 30% bandwidth.
