A high-performance S-band power amplifier fabricated on a low-cost 20-mil-thick FR-4 printed circuit board (PCB) for S-band radar applications is demonstrated. The amplifier consists of a single-ended driver stage and a balanced output power stage utilizing Wilkinxon power dividers/combiners with quarter-wave transmission lines. Under 10-V and 2.45-A dc bias condition, the S-band power amplifier with 23-dB small-signal gain, 38-dBm 1-dB gain-compression power with 25.6% power-added efficiency (PAE) and 3.9-dB noise figure can be achieved. In addition, excellent linearity with a 48.73-dBm 3 rd-order intercept point is also measured.
