Abstract
Different HBTs operating classes have been compared using a simulated multiharmonic load-pull type optimization taking into account the supply voltage criteria. The optimum operating class taking into account the power density and the thermal effect has been discussed. The low bias voltage operation of HBT has been investigated. An HBT amplifier has been designed and fabricated for DCS1800. 1 W output power with a power-added efficiency df 50% has been measured.
