Abstract

In this paper we present the compression analysis of a BJT high power amplifier circuit. This circuit was chosen by Microwave Engineering Europe (MEE) as a challenge to CAD programs. The bipolar transistor is modeled by a SPICE model. Extraction of the model parameters was performed by fitting the model responses to vendor-published S-parameter data. In addition to compression analysis of the amplifier, we carried out Monte Carlo statistical simulation and sensitivity analysis. All simulations and optimizations were performed by our CAD software system OSA90/hope, in particular by our nonlinear harmonic balance simulator
