Abstract

In this paper, a C-band active integrated antenna push-pull power amplifier is presented. The circuit utilizes a uniplanar quasi-Yagi antenna with corrugated ground plane for both out-of-phase power combining and second harmonic tuning. This novel structure results in a compact and high-efficiency power amplifier design with automatic second harmonic suppression. At an operating frequency of 4.15 GHz, a maximum measured PAE of 60.9% at an output power of 28.2 dBm has been achieved.
