Characterizing RF Ampliiers – Measurement Parameters

S-parameters/stability factor

Traditionally, S-parameters (both relection and transmission) measurements have been performed with VNAs. As well as basic S-parameters of devices, designers and manufacturers have to carefully look into various parameters calculated from the S-parameters. K-factor is one of the examples and a signiicant parameter especially for ampliier designers. This factor can be calculated from all the S-parameters of two-port devices (S11 to S22), and represents the stability of ampliiers. When K-factor is greater than 1 while delta is smaller than 1, the ampliier is unconditionally stable and no oscillation is expected for any load.
