Abstract
A differential power amplifier includes an input matching network, a first-stage amplification circuit, a first inter-stage matching network, a second-stage amplification circuit, a second inter-stage matching network, a third-stage amplification circuit, and an output matching network. The first-stage amplification circuit and the second-stage amplification circuit are single-ended input single-ended output circuits. The third-stage amplification circuit is a dual input dual output circuit. The second inter-stage matching network includes a first transformer T, a first capacitor C, a second capacitor C, a first inductor L, and a second inductor L. The output matching network includes a second transformer T. The inter-stage matching networks and the output matching network are realized by the first transformer Tand the second transformer T, which reduces an inter-stage matching difficulty, optimizes input return loss and gain, and improves output power.
