A Proof-of-Concept (PoC) of a wideband Power Amplifier (PA) with controlled efficiency based on second har-monic matching is proposed in this paper. The context of carrier aggregation in the 5G standard needs wide operating bandwidth with high Power Added Efficiency (PAE). Thus, the output network uses harmonic processing techniques to control the PAE over the bandwidth (BW) from 0.65 to 1.5GHz. The gain is between 9.2 and 12.2dB, Psat is between 24.2 and 27.2 dBm, and the PAEmax is between 42.5 % and 57 % with a best improvement of 16 points at 1.4GHz.< Leer menos
