Abstract

Totem pole class B envelope tracking supply modulator is generally consisting of two single ended transistors operating in anti-phase. In this paper, the totem pole class B supply modulator design consists of two transformers that are used to split the input signal and to combine the output signal. The totem pole consists of two N-channel BJTs connected where the output is taken to the second transformer. The result shows that the designed supply modulator is able to operate in wide bandwidth from 100MHz to 1 GHz. This supply modulator works as hybrid supply modulator which the DC signal will be combined with the high frequency signal at the transformer.
