Abstract :
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 influences are also presented.
