JFW has recently added four new models to their website. They are conduction cooled (bolt down) type 50 Ohm terminations. 

Four attenuator assemblies have been added tot he JFW website. These attenuator assemblies operate at 200 to 7125 MHz with attenuation range 0 to 95 dB by 1 dB steps.

One challenge facing test engineers charged to evaluating today’s complicated wireless networks & devices is the sheer number of potential RF connections requiring scrutiny. Readers will learn how RF switch matrices can extend the port count of VNAs to meet the testing demands of modern wireless standards & sensing technologies.

JFW added a line of 50 Ω solid-state RF switches that operate from 20 MHz to 8 GHz. 

A 50 Ohm USB attenuator to help automate your Wi-Fi 6E testing. 50P-2111 SMA operates from 200 MHz to 8 GHz with attenuation range 0 to 95 dB by 1dB steps. 

JFW’s 50S-2133 SMA is a self-terminating 1P8T RF switch. 

50BR-160 is a benchtop 50 Ohm manual attenuator. It has an attenuation range 0 to 121 dB by 1 dB steps with an average RF power rating of 1 W.

50PA-1174-XX is a remotely-controlled attenuator assembly containing up to 8 attenuators that operate from 200 MHz to 8 GHz. 

50PA-1068 is a controller module which can be connected up to as many as 8 attenuator modules. The SMA version has 24 attenuators per module.
