Abstract
A driver for a switching power amplifier is designed by an iterative least squares method. With only one stub and two lines in each input and output matching network, amplitude and phase responses up to ninth-order harmonic frequencies have been controlled. The designed amplifier is built, and the method is verified with measurements.
