90WVA-20 WR90 Waveguide Variable Attenuator 8.2-12.4GHz with Two Rectangular Waveguide Interfaces

Quick Overview

WR90 Waveguide Variable Attenuator Operating From 8.2 to 12.4GHz with Two Rectangular Waveguide Interfaces

Availability:In stock

Description

Waveguide variable attenuator 90WVA-20, operating from 8.2-12.4GHz,has a 0.15dB insertion loss, low VSWR 1.20:1, and up to 20dB nominal attenuation. 90WVA-20 covers the WR90 full waveguide band and comes with two flanges FBP100(UBR100). It can handle 4W continuously and 4KW peak power. The variable attenuator has a precision micrometer allowing for repeatable attenuation settings. The A-INFO's waveguide variable attenuator is manufactured with a high precision machining process to ensure high quality and ruggedness. The variable attenuator is an ideal component of equipment in waveguide systems where broadband attenuation is required. They are ideal for radar antenna systems, laboratory test set-ups, microwave radio, satellite communications, and other applications requiring low insertion loss, and low return loss. Different flange types may be available in stock, and please contact us to inquire further.
