Abstract :
A nonlinear model of a Schottky diode was developed that is suitable for application in microwave mixer circuits. The model was used in the design of a microwave balanced mixer. The mixer circuit was analyzed using a general nonlinear circuit simulation program. The results of the simulation and measurements are in very close agreement, which indicates the validity of the diode model and the accuracy of the simulation program. The designed mixer has a conversion loss of 6 dB and a noise figure of 6 dB.<>
