WiMAX Power Amplifier Design Based On Si-LDMOS

technology processes such as Gallium-Arsenide (GaAs) to obtain the performance needed from the RF circuits. Although these technologies provide the functional performance required by radios today, they do not support the cost/scalability business model. This paper outline the design of a power amplifier (PA) for WiMAX base station applications at 3.5GHz based on cheap Si-LDMOS technology developed for 2Ghz applications and analyze the behavior of the design regarding nonlinear distortion. The design showed an acceptable power performance, a good gain and a memoryless behavior. I
