摘要
In this paper, a D-band power amplifier (PA) based on 0.5-mu m InP DHBT is presented. Wilkinson combiners with broadband stepped impedance matching are used, and the eight-way PA is designed for wide-band power performance. As input power is fixed at 3 dBm, the PA exhibits a saturated output power of 16.8dBm and 7.9% PAE at 150 GHz with >45-GHz 3-dB power bandwidth from 125 GHz to 170 GHz. Meanwhile the 1-dB gain compression output power is 15.9dBm at 150 GHz. The >45-GHz 3-dB power bandwidth means a great flatness of power gain which is outstanding in reported D-band PAs to our best knowledge.
