An mm-Wave Multi-Mode Asymmetric Power Amplifier With Back-off Efficiency Enhancement

This paper presents a multi-mode asymmetric power amplifier (MMA-PA) with back-off efficiency enhanced. The back-off efficiency is improved without a lossy impedance inverter or signal separator which is used in conventional Doherty or outphasing amplifiers. The design considerations are provided in...
