Abstract :
This paper presents a new method, which is derived from the circuit envelope method. This method is intended for the analysis of the microwave circuit excited by digitally modulated signal, especially the FDMA signal, which employs a lot of carriers. Compared with conventional circuit envelope method, this method possesses a higher speed, and required smaller memory. A power amplifier excited by QPSK signal is analyzed in a good agreement with the theoretical deduction
