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).

Understanding Power Divider/Combiner Types And Functionality
5/7/2018
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. This white paper offers guidelines and considerations for determining a divider/combiner for each application.

An Introduction To Programmable Attenuator Systems
12/7/2017
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 app note discusses key components in a programmable attenuator system, as well as the best choices for general applications.
