RF Receivers (electronic listening devices) Are Ideally Suited For Using RF Reed Relays

Introduction

 

With the continuous worldwide threat of terrorism, most countries need to be monitoring all electronic communication on a 24/7 basis. Most of this is done with electronic receivers scanning all the RF ranges where potential communication may take place. RF switches are needed to switch from scanner to scanner without affecting the very small signals that are potentially being received. Using RF semiconductors can be very expensive and suffer from inter modular distortion, while electromechanical relays are large, bulky and expensive. Standex Electronics’s continually advancing RF reed relays are ideally suited for this application.

Electronic Receivers Use Reed Relays

Today terrorism is the most feared subject in the world. Monitoring world communications can act as a deterrent by supplying potential early warnings preventing potential calamities about to occur. Having sophisticated electronic scanning receivers that have the ability to scan large frequency bands in an efficient manner is a key requirement.
