A 35.6dB, 43.3% PAE class E differential power amplifier in 2.4GHz with cross coupling neutralization for IoT applications

In this paper a novel class E power amplifier with high efficiency and low power consumption for internet of things (IOT) application is presented. It is shown that employing cross coupling neutralization and fully differential topology in class E power amplifier lead to high power efficiency, high power gain and better reverse isolation. The proposed class E amplifier can achieve 28.5 dBm output power to a 50Ω load at 2.4 GHz with 43.6% power added efficiency and 35.6 dB power gain. These results are verified by the circuit level simulations of the proposed PA that performed by 0.18μm standard CMOS technology.
