National Instruments has released a new application note detailing how to design RF/microwave amplifiers when only S-parameter data of the transistor is available.

The application note describes a method to be used within the AWR Design Environment which can be used for low-noise, high-power, narrowband and multi-octave bandwidth amplifiers whether or not nonlinear transistor models are available.

The technique originated by Dr. Steve Cripps of Cardiff University is an extension of the Load-Line approach and further developed using the power parameters technique introduced by Pieter Abrie in the MultiMatch Amplifier Design Wizard, which generates the desired matching circuit schematic in the NI AWR Design Environment.
