Wideband Sequential Circulator Load Modulated Amplifier with Back-off Efficiency Enhancement
Paper in proceeding, 2022
at 8-dB output power back-off across 2.0-3.0 GHz. Combined with the measured peak output power of 42.7±0.7 dBm in the same range, make it a promising candidate for use in modern energy-efficient wireless communication transmitters.
