09.08.21 -- The Basics Of Passive RF Test Systems & Components For Wireless Testing

 
 
 
Introduction To RF Matrix Switch Types And Functionality
 

There are many types of RF matrix switches with configurations that distribute RF signals in very different fashions. Learn the functionality of these types of switches, their advantages and disadvantages, and how to choose the best switch for each application, in this application note.

An Introduction To Programmable Attenuator Systems
 

A programmable or step attenuator is externally controlled with maximum attenuation ranges from 0 dB to 127 dB, in steps as small as 0.1 dB. This application note discusses the key components in a programmable attenuator system, as well as the best choices for general applications.

Understanding Power Divider/Combiner Types And Functionality
 

Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. Read this article to learn the guidelines and considerations for determining a divider/combiner for each application.
