Right Size Testing


How to Right Size
Your Wireless Testing

As today's wireless networks become more and more complex, so do the requirements for testing them.
JFW Industries has put together a helpful instruction on how to make sure that the RF test system you choose is the right one for your network and you budget.


Introducing JFW's newest family of manual, rotary attenuators... now offering more attenuation than ever before at 3 GHz and beyond. The single-rotor, 50R-397 is DC-3GHz with 0-70dB in 10dB steps; while our bench-top assembly, the 50BR-147 allows for up to 110dB in 1dB increments. This family also includes two versions of our versatile dual-rotary attenuators, which can be easily integrated into RF systems for OEM or test applications. The 50DR-143 offers 0-80dB x 1dB of attenuation from DC-3GHz and the 50DR-141 goes all the way from DC-3.6GHz with a dynamic range of 0-40dB in 1dB steps.



New 40 GHz Fixed Attenuators

Introducing the 50HFAH-XX 2.9MM and 50T-274 2.9MM M,

JFW's first ever DC-40-GHz fixed attenuators and RF terminations.

The 50T-274 2.9MM M is rated at 1 Watt and has an impressive VSWR of 1.2:1 maximum, while the 50FHAH series of attenuators handles 0.5 Watts with a maximum VSWR of 1.4:1.

Both come standard with 2.9MM connectors
(attenuators are male/female, terminations are male).
