Recent MMlC technology advancements, both in PHEMT devices and in new integated power circuit techniques, allow pace setting power amplifier performance to be achieved. This combination has been key to realizing the full cost@erformance inherent in MMlC power technology. This paper describes two advanced MMlC power amplifiers covering the 6-18 GHz and 8-14.5 GHz bands. Both chips are based on a novel two section distributed amplier structure that employs bandpass networks instead of the convenSonal lowpass image-parameter networks. A new mabix amplifier structure is also used in the first stage of the 8-14.5 GHz PA. Bias networks are fully integated to allow automated assembly. Significant milestones in wideband power and efficiency have been achieved.

A GaAs broadband, dual-channel high-efficiency power amplifier MMlC is presented in this paper. The average performance for a single channel of the power amplifier is 18.0 dB small-signal gain, 16% power-added efficiency, and 2 dB compressed output power of 29.4 dBm from 6 to 18 GHz at 25°C. The two channels combined off chip achieve 32 dBm average output power. This 0.5 pm ion-implanted MESFET amplifier MMlC has been demonstrated in volume production with 154 wafer starts over 3 months resulting in a 30% total yield through fixtured RF test.
