Heterostructure Barrier Varactor Multipliers
Paper i proceeding, 1998
We describe the Heterostructure Barrier Varactor (HBV) diode and its application in frequency multipliers. Different varactor models are presented that easily can be used in large signal simulations. Results from frequency multiplier measurements are presented. The delivered maximum output power at 234 GHz is 3.6 mW. Simulations show that the output power is limited by excessive conduction current due to increased diode temperature.
