Abstract
High Efficiency power amplifier for cellular base station is in high demand as 5G infrastructure will include more cells in order to cover denser areas of transport. High Efficiency power amplifiers are demanded, as they serve a key bottle neck in each cell. high efficiency power amplifier is introduced with peak power of 70W in a range of 2Ghz-3.6Ghz bandwidth with 50-62% efficiency. The design makes harmonic engineering till the 3rd harmonic at the output and at the input of the power amplifier, in order to reach the highest efficiency. The amplifier is tested with a 40Mhz LTE signal with DPD implementation..
