Low-Noise and High-Efficiency Microwave Power Amplifiers: A Review of Advanced Circuit Techniques
Abstract: Microwave power amplifiers (PAs) are essential components of wireless transmitters, radar systems, satellite links, and microwave instrumentation. Their principal task is to deliver sufficient radio-frequency output power to a load while meeting requirements for efficiency, linearity, gain, bandwidth, stability, and spectral compliance. Modern communication waveforms, particularly OFDM and high-order modulation, exhibit high peak-to-average power ratios (PAPR), forcing conventional PAs to operate with substantial output back-off and often reducing average efficiency. …
