The design and simulation of a Class-E power amplifier with an Inverse Class-B driver are presented. The Inverse Class-B amplifier generates a train of half sinusoids which provides a compromise between using a sine wave and a square wave as the input waveform. The design methodology proposed includes the use of load-pull technique to determine the optimum fundamental-frequency load-impedance of the amplifiers, and a series LC resonator to improve the second-harmonic suppression level. The PA exhibited 26.3 dB gain and 57% PAE at an output power of 21.3 dBm with the second and third harmonics attenuated to 38 and 37.3 dBc respectively.
