OVERVIEW
Description
Virginia Diodes offers zero biased, Schottky diode detectors for a variety of millimeter wave and Terahertz applications. These detectors provide high responsivity and extremely fast response time. VDI detectors offer full waveguide band coverage and are available from WR15 (50-75 GHz) to WR0.65 (1100-1700 GHz). Higher frequency custom detectors are available upon request.
Configurations (ZBD vs. ZBD-F):
ZERO BIAS DETECTOR

Notes:
*Typical Responsivity assumes optimal RF input power applied to ZBD. Higher RF input power will
reduce responsivity.
**Maximum Response Rate applies to Fast Detectors only (ZBD-F configuration).
