Designing complex analog systems needs different abstraction levels to reduce the overall complexity. The required level of abstraction depends on the accuracy and the purpose of the model. High-frequency amplifier models can vary from simple transfer functions for efficient bit-error- rate analysis up to detailed transistor level descriptions for accurate load-pull prediction. This paper introduces a nonlinear black-box model for high-frequency amplifiers. It extends the linear S-parameter representation to enable both efficient system-level simulations and load-pull prediction. Both are demonstrated on the measurements of a high-frequency amplifier excited using a WLAN - OFDM modulation.
