Abstract

A 1-20 GHz distributed power amplifier (DPA) with a novel compact structure is designed and implemented in a commercial 0.18 μm CMOS technology. The proposed DPA consists of two distributed amplifiers (DAs), which have separate input artificial transmission lines (ATLs) but with their output ATLs shared to achieve high output power and efficiency in the wide frequency band. The gradually changed output ATL is used to further improve the power performance. Measurement results show that the DPA achieves 9.6 dB average associated gain from 1 to 20 GHz. The output power at 1-dB output compression point (OP1dB) is more than 8.2 dBm, and the peak power-added efficiency (PAE) is 9.6% with the OP1dB of 12.9 dBm at 4 GHz.
