Abstract : A procedure which uses microstrip matching circuits was formulated for designing L-band transistor power amplifiers. The procedure uses a precision measurement technique for transistor impedances and an optimization routine for realizing the required matching circuits in microstrip. A model for large step discontinuities in microstrip was developed and was included in a computer optimization program. Good agreement was obtained between measured and calculated microstrip circuit impedances. The computer-aided procedure was used to develop L-band, class C, pulse-operated transistor power amplifiers. Significant improvement was obtained in power gain, bandwidth, and collector efficiency over amplifiers designed by more conventional methods. (Author)
