Abstract

The power amplifier is becoming most challenging modules to design in a wireless communication system. Also, a wireless communication is demanding multi-band transmitter and receiver, so the design to get optimum efficiency and linearity in power amplifiers in multi-band applications becomes more and more challenging day by day. As such, a lot of work has been performed to design highly efficient and linear power amplifiers. The basic class E power amplifier and the cascode circuit of the class E power amplifier has been implemented and operated at two different frequencies (1.7GHz and 2.4GHz) to see the effect on the linearity parameter of PA. The voltage supply of 2.5V has been used and the input power of 12dBm. The simulation results clearly depict the linearity of the circuit with 50 ohm load.
