摘要：A primary drawbacks of conventional outphasing power amplifier are the requirement of both a RadioFrequency (RF) carrier input and a separate baseband input to synthesize a modulated RF output. This work focuses onRF power amplifier with avoiding the need for multiple costly IQ modulators and baseband signal componentseparation. An RF signal decomposition network directly synthesizes the amplitude and phase-modulated signals usedto drive the branch power amplifiers (PAs). The proposed technique is demonstrated at a frequency range of 2.4 – 2.45GHz power amplifier which is a four-way lossless power amplifier with transmission line power combiner. Theproposed technique overcomes the loss and provides ideally lossless power combining. A transmission line resistivecompression network is used to implement RF decomposition network. The resulting four-way lossless RF poweramplifier gives 1 dB drain efficiency of 77.31 % and output power of 95.45 – 99.83 W along with 11.79 dB gain.
