An 89 GHz waveguide coupled direct detector based on a low-barrier Schottky diode is presented. The main focus is to reduce white and 1/f noise to achieve high signal-to-noise ratio values above 35 dB. The design also ...

Zero-bias Schottky diode detectors operated at room-temperature are the choice for applications, where the ultimate sensitivity of a cryogenic detector is not needed. Furthermore Schottky detectors are intrinsically much ...

We present ultra-wideband zero-bias Schottky diode detector modules with monolithically integrated log-spiral antenna. Detectors exhibit a broad-band response with a stronger roll-off above 800 GHz and the minimum ...
