Zero-Biased Detectors

Features

  • 26.5 to 220 GHz
  • High sensitivity
  • No bias
  • Compact design
  • High reliability
  • Rugged construction
Applications
  • Laboratory measurement and test equipment

Outline drawing of ZBD-06 detector

 Typical sensitivity and linearity data presented in the plot below.

     Detectors of ZBDA-XX series supplied with built-in buffer amplifier at ZBD output. The amplifier protects Schottky diode against wrong actions (short circuit at output, static electricity) and helps increase reliability of ZBDA-XX detectors. The ZBDA-XX detectors are fed with DC bias voltage (+5VDC…+10VDC). 

How to order

Specify Model Number ZBD(A)-XX/F/P, where

A   - means output power amplifier exists 

XX – number of waveguide standard (Ex. 10 for WR-10 and 06 for WR-06) 

F   - central frequency (or operating range), nothing if full band 

P   – max input power level in mW 

 

Examples

ZBD-10/20, W-band detector, full operating bandwidth, max input power 20 mW

ZBD-10/92-96/10, W-band detector, operating bandwidth 92-96 GHz, max input power 10 mW

ZBDA-06/140/70, D-band detector with built-in power amplifier, central frequency 140 GHz, max input power 70 mW
