Abstract
We present a method for characterizing three-port (RF, IF, image) conversion scattering parameters for microwave mixers. A diplexer is used to separate the image signal from the IF signal. The de-embedding and un-terminating methods have been used for calculating the scattering-parameter matrix. The conversion scattering parameters have been obtained at different local-oscillator (LO) power levels for a commercial microwave mixer. We also show how the termination of the image signal will affect the conversion loss of the microwave mixer.
