Abstract

In this letter, a dual-band class-E CMOS power amplifier (PA) in 0.18-μm CMOS process is presented. By using concurrent dual-band impedance matching network, the proposed dual-band PA can achieve high efficiency in a compact chip area. This dual-band class-E PA demonstrates the power gain ≥ 8.4 dB, Psat ≥ 21.4 dBm with power added efficiency ≥ 31% in a compact chip size of 0.5 mm2. This dual-band class-E PA achieves comparable power area density of 284.5 (mW/mm2) with other state-of-the-art class-E PAs at higher frequency.
