| contents | <p>Pulse-Width Modulation (PWM) based Class-D Radio-Frequency Power Amplifiers (RF PAs) have emerged as a promising solution for achieving high efficiency in modern wireless communication systems. Unlike conventional linear RF PAs, Class-D amplifiers operate as high-speed switches, reducing power losses and enabling efficiencies above 80%. In this work, a PWM-controlled Class-D RF PA is designed and analyzed to enhance spectral purity, linearity, and power conversion efficiency. Simulation and experimental results demonstrate that the proposed architecture achieves stable operation at RF frequencies with reduced harmonic distortion, making it suitable for broadband and high-data-rate transmission. The findings highlight the potential of PWM-driven Class-D RF PAs in next-generation communication systems, where low power consumption and high performance are critical.</p> |
