Abstract

A sub-millimeter(mm)-wave detector module implementing an InP-based zero-biased Schottky-barrier diode (SBD) has been fabricated. The SBD is monolithically integrated with a short-stub resonant matching circuit for increasing the detection sensitivity as well as providing a biasing circuit. The SBD chip is mounted in a compact J-band (WR-3) rectangular-waveguide-input module for practical use. The module exhibits a peak sensitivity at around 350 GHz due to the characteristics of the matching circuit, and a good linearity of the output voltage against the input sub-mm-wave power. A record sensitivity of 1460 V/W is obtained for the InP-based zero-biased SBD at 350 GHz.
