– Typical characteristics of sensitivity with a load resistance of 1 MΩ are presented in the graphs below.
– Typical dependence of output voltage on input power  with a load resistance of 50Ω is also presented in the graph.
– To protect the Schottky diode, we recommend using a high-resistance load or a video amplifier.

Note: Max input power level into a detector can be increased by installing the built-in attenuator.
It will cause a decrease in sensitivity correspondingly.

DETECTORS with a built-in video amplifier (OPTION)

Detectors of the ZBDA-XX series come equipped with a built-in video amplifier at the ZBD output. This amplifier serves to protect the Schottky diode against incorrect actions, such as a short circuit at the output or static electricity, thereby enhancing the reliability of ZBDA-XX detectors. These ZBDA-XX detectors operate with a supply voltage in the range of -15VDC to +15VDC. Standard amplifier parameters are presented in the table below

How to order Zero-Biased Detectors

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

A   – means the output power amplifier added
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
