In this paper a new cascode class E power amplifier with a driving stage of class F and novel output network is proposed. Class F power Amplifier is able to produce square waves, used in driving of main stage, owing to use main frequency and third frequency harmonic. The proposed output network has also improved the parameters of circuit like efficiency, power added efficiency and output power with adding a capacitor and an inductor. In order to have more real results the circuit has been redesigned and simulated using spiral inductors.The simulation has taken place using ۰.۱۸ µm CMOS technology in ADS simulator software based on IEEE ۸۰۲. ۱۱b utilized in ۲.۴ GHz and WLAN applications. Proposed circuit delivers ۲۳.۱ dBm power; out of a ۱.۸ supply voltage to a ۵۰Ω load with ۸۴.۳% efficiency and ۸۰.۴ % power added efficiency in ۲.۴ GHZ operating frequency.
