In this work, a switched-device power amplier using bias control is designed and realized. The PA operates at a frequency of 100MHz. Test results show that the PA achieves a PAE of 63% at −6dB power back-off and 60% at the peak output power of 40dBm. First, an overview of the state-of-the-art PA technology and performance in high PAPR applications is given. The state-of-the-art analysis is then used to set up the requirements of the PA and to compare the results to in the end. The design of the PA is explained in detail, followed by an evaluation of the simulated and measured results. Notable observations of the performance measurements are also discussed. After the concluding remarks regarding this work are given, recommendations on how to improve the performance and to extend the concept of the proposed switched-device PA are presented.
