Abstract
This paper presents a high power, high efficiency power amplifier using GaN HEMT class F inverse with harmonic termination network at operating frequency 2.14GHZ. The optimum impedances for input and output 1 st ,2 nd , and 3 rd harmonics were extracted using load and source pull analysis. Effect of with and without harmonic termination on the performance of class F inverse power amplifier is evaluated by its output power, PAE and gate stress. Propose class F inverse amplifier is fabricated on RO4350B. Measured results indicate that class F inverse power amplifier has achieved high output power 36.3dBm with high efficiency of 71%.
