A quantitative comparison between calculated and measured conversion losses of a novel beam-lead GaAs Schottky-Barrier mixer diode with minimized parasitics

The conversion loss of a mixer diode is calculated as functions of the diode characteristics including the ideal
n
-factor. Good agreement between the calculated and measured results is demonstrated by using both a novel beam-lead GaAs mixer diode with minimized parasitics and an improved test fixture for measuring the loss of this device.
