This paper presents a multi-mode asymmetric power amplifier (MMA-PA) with back-off efficiency enhanced. The is improved without lossy impedance inverter or signal separator which used in conventional Doherty outphasing amplifiers. design considerations are provided detail. In addition, the proposed MMA-PA operates three different modes according to input level. PA fabricated 65-nm bulk CMOS tec...

This article introduces a four-element 300-GHz-band bi-directional phased-array transceiver (TRX). The TRX utilizes the same antenna, signal path, and local oscillator (LO) circuitry to operate either in transmitter (TX) mode or receiver (RX) mode. TX adopts outphasing technique increase average output power for higher order modulation schemes by utilizing two mixers that are connected directly...

This paper discusses about systematic design approach of Reactance Compensated Class-E. The theory behind conventional Class-E is described then differences between Compensation explained and derived. reactance compensated gives better high efficiency bandwidth. range shunt capacitor value that can maintain operation also increases compared to overall impedance for derived shows it the same as ...
