Abstract :
A large-signal, two-stage power amplifier design approach using the waveform-balance method is presented. The MMIC (monolithic microwave integrated circuit) amplifier designed by this technique is shown to have a state-of-the-art power and efficiency performance at X-band. The amplifier has 40% bandwidth, 2 to 3-W CW output power, 10-dB power gain, and greater than 30% power-added efficiency across most of the frequency band.<>
