VDI offers zero biased detectors (ZBD) for a variety of mmWave and THz applications. These detectors offer full waveguide band operation, high sensitivity, and high responsivity. Planar construction yields a mechanically robust design. VDI ZBDs are compact and simple to use. Our broad band Quasi-Optical ZBD (QOD)  covers the entire 100 GHz to >1 THz band with a single device.
