Abstract :
A silicon MMIC power amplifier delivers over 1 W of output power at 830 MHz. When biased in class AB, this amplifier provides a 30 dB power gain, a 30% power-add-efficiency (PAE), and 50 dB dynamic gain-control range. This amplifier uses on-chip spiral inductors to provide interstage impedance matching, and incorporates negative impedance cancellation in one stage to boost gain and impedance level. Temperature-compensated biasing provides accurate control of the quiescent current in each amplifier stage.
