Abstract :
A procedure for the design of broadband large-signal amplifiers is presented. The method is based on extraction of bias-dependent small-signal S-parameters from the nonlinear device model. A broadband matching technique is used to obtain flat power gain at the band of interest while suppressing unwanted harmonics. The procedure has been used to design octave-band GaAs FET amplifiers. Simulation results using the harmonic balance technique verify the effectiveness of the procedure
