Abstract:
We report on the design, build and characterisation of an integrated submillimetre wave receiver featuring a 380 GHz sub-harmonic mixer and a 190 GHz frequency doubler on a single quartz based microstrip circuit. The integrated circuit uses two separate planar Schottky diode components to perform the doubling and 2nd harmonic mixing. Measurement results give best double sideband mixer noise temperatures of 1625 K at 372 GHz, and a corresponding mixer conversion loss of 8 dB. The measured instantaneous RF bandwidth extends from 368 GHz to 392 GHz, in good agreement with simulations. This work represents the first demonstration of a single substrate integrated mixer/multiplier at submillimetre wavelengths.
