Abstract :
The development of a 750-GHz Schottky varactor diode frequency tripler having a measured output power and efficiency of more than 120 μW and 0.8% at a frequency of 803 GHz is described. The output powers and efficiencies are the highest reported for this frequency. The 750-GHz tripler mount is analyzed and optimized using a scaled model of the mount. Measurements of the embedding impedance seen by the device, using the model, are compared with theoretical values
