Abstract
A power amplifier includes a transistor, a transmission line transformer, and a capacitor. The transistor is operable to receive a signal and to generate an amplified signal. The transistor has a source, a drain, and a gate. The gate has a first impedance and is operable to receive the signal to be amplified. The transmission line transformer has a first, second, third, and fourth port, the first port and the third port being coupled directly to the gate of the transistor, and the fourth port being coupled to a source device having a second impedance. The capacitor has a first end and a second end. The first end of the capacitor is coupled to the second port of the transmission line transformer and the second end is coupled to a ground.
