Abstract
A new behavioural model of a power amplifier (PA) at system level is presented, dedicated to radar applications. This model, which is able to take into account output loading impedance mismatch, is based on a similar topology to the PA´s circuit. The model, implemented in Agilent Advanced Design System (ADS), is validated for different loading impedances, until VSWR=2 (voltage standing wave ratio), on the PA´s bandwidth. This approach permits an extraction, resulting from simple CW measurements or simulations, and easy model implementation. This work has been supported by DGA (French Defense and Security Agency)
