Monolithic HBV-Based 282-GHz Tripler With 31-mW Output Power

Journal article, 2012

We present a heterostructure barrier varactor multiplier at 282 GHz. The tripler chip was monolithically fabricated in the InGaAs/InAlAs material system on InP as carrier substrate and mounted in a fix-tuned, waveguide block. Standard rectangular waveguides WR-10/WR-3 connect the multiplier chip to the respective input/output of the waveguide block. Measurements produced 31 mW of output power and a minimum conversion loss of 11.6 dB (7 % efficiency). The device dimensions and their electrical and thermal influence are also presented.
