摘要
In this paper, we present a dual-band Sequential Power Amplifier (SPA) to provide high efficiency at power back-offs and maximum output power at two working frequencies. The proposed SPA consists of a carrier amplifier, a peaking amplifier, a power divider and a combining coupler. The SPA provides 48 % and 62 % drain efficiency (DE) at 6 dB output back-off (OBO) and maximum output power at 1.1 GHz, and it also provides 52 % and 65 % DE at 6 dB OBO and maximum output power at 1.5 GHz. The designed SPA achieves above 39 dBm output powers at two working frequencies with about 10 dB gain and +/- 1 dB gain flatness.
