Description
There is a strong demand for compact, room temperature sources at millimetre waves and THz frequencies for various applications in space as well as terrestrial.
At frequencies above 150 GHz multipliers are producing state-of-the-art power levels. Even though it is mainly multipliers based on the more mature Schottky technology, HBV based multipliers have a number of advantages. They only generate odd harmonics and can operate bias free, which simplifies circuit complexity. The HBV can easily be scaled by increasing the number of barriers to manage higher powers. With the advent of W-band amplifiers producing Watts of output power, the HBV tripler (x3) to 300 GHz and quintupler (x5) to 500-600 GHz seems as commercially viable products.
In this project we have investigated a suitable passivation material for the HBV, which would ‘seal’ the devices surface, which could be prone to degradation otherwise. In addition, the passivation is expected to reduce the device leakage current that might further improve multiplier performance and lifetime.
Finally, suggestions for taking the HBV multiplier reliability assessment further have been discussed at the end of the report.
