A Novel Method for the Analysis of Microwave Two-Port Active Mixers (Short Paper)

An analysis method for a microwave mixer, based on an active nonlinear device, is developed. The method is a two-port extension of Kerr's work on a one-port (diode)-type mixer and utilizes the harmonic balance approach for the large-signal analysis portion. It results in a relatively fast and efficient program, the use of which is demonstrated by simulating the operation of a mixer based on a NEC MESFET for a range of local oscillator available power and frequency conditions.
