Linearity-Enhanced and Highly Efficient Doherty Power Amplifier: 16th High Efficiency Power Amplifier Student Design Competition

The 16th High Efficiency Power Amplifier (HEPA) Student Design Competition (SDC), organized by the IEEE Microwave Theory and Techniques Society, was held virtually in collaboration with Keysight Microwave Laboratory for the live measurement. This contest focuses on the PAs that have both high efficiency and high linearity over a relatively broad bandwidth. The participants are required to design and fabricate a highly efficient, linear power amplifier (PA) at a frequency of their choice between 1 and 10 GHz. The winning team is determined by the designed PA's highest linear power added efficiency (PAE) at the lowest output power level while maintaining a carrier-to-intermodulation (C/I) ratio of greater than 30 dB through a two-tone input signal measurement. To have a competitive entry in the contest, it is necessary to start with the statement of the competition's rules.
