Abstract
An extended version of the Volterra model for wideband amplifiers and its efficiency are analysed. A 2-MHz wideband code division multiple access-like waveform is used as probing signal in order to model a 915 MHz, 34 dB-gain amplifier. The experimental envelope output samples of the amplifier driven near the 1-dB compression point are used to extract the Volterra kernels and comparison of the calculated and measured signals has shown a high correspondence. Result shows that the proposed model exhibited a good capability of predicting the output response with a different signal excitation.
