electroRF Member Jun 23, 2012 #1 My final year project is designing a power amplifier with a bias control network and an open loop power control system. The system looks like that: View attachment 65111 The 2-Stage PA looks like that: View attachment 65112 Firstly, I'd like to focus on the 2-stage PA itself, disregarding the bias network and OLPC system. I'd like to bias it in class AB. My main goal is to maintain high efficiency. How do I start? What kind of simulations shall I run? The PA should maintain an output power of 1W. The input signal frequency is 5.8GHz. I'd appreciate your guiding folks. Thanks. Last edited: Jun 23, 2012
