| Abstract: | A novel design technique for increasing Power Added Efficiency(PAE)of RF power amplifier is demonstrated.PAE is increased by reducing the 2~(nd)harmonic element and reflecting the 3~(rd)harmonic element,and phase matching is accounted for this design.A power amplifier for experimental verification is designed and fabricated based on this topology,simulation and measurement results show that;its power gain reaches up to 20 dB,output power is 30.05 dBm at 1 dB gain compression point,and the maximum PAE comes up to around 58.75%which is 12%higher than conventional power amplifiers at 918 MHz operation frequency. |
| Keywords: | phase matching harmonics controlling PAE power amplifier |
