Claim Text:
1. A differential power amplifier comprising: a first push-pull pair of transistors including a first capacitance connected to (i) the output terminal of the first transistor, and (ii) the input terminal of the second transistor, wherein harmonics at the output terminal of the first transistor combine with harmonics at the input terminal of the second transistor via the first capacitance such that the harmonics at the output terminal of the first transistor and the harmonics at the input terminal of the second transistor cancel; a first inductance, wherein the first transistor and the first inductance are connected in series between a voltage source and a reference terminal; a second inductance, wherein the second transistor and the second inductance are connected in series between the voltage source and the reference terminal; and a second capacitance connected in parallel with the first inductance or the second inductance.
