A Day In The Life Of An RF/Microwave Attenuator
4/14/2022
Fixed RF attenuators are versatile components that not only provide useful level control features but can be used to enhance the return loss at the input of a mismatched component/device in the signal chain. This article explains how RF fixed attenuators are used in hopes of improving the VSWR within the signal chain.

Transceiver Testing By JFW Industries
12/3/2019
JFW's family of RF test systems designed for transceiver testing connects multiple radios together in a closed mesh network configuration. Variable step attenuators allow you to dynamically fade up/down the RF signal between radios. Available in three different basic configurations to simulate almost any network topology (custom configurations available upon request).
