| Abstract: | To obtain optimum geometry dimensions of beam lead Schottky barrier Mixer diode byusing CAD method based on Pucel models of planar capacitor and Berger models of planarresistor.The total capacitance and total resistance of the diode to be minimuin in order toincrease the cut-off frequency and improve the noise characteristics for a certain condition.The typical value of the DSB noise figure of the mixer diode is 4.8 dB at 35 GHz,which ac-cord with the prospection. |
