18 GHz Step Attenuators w/ TTL, USB, or Ethernet Controls

18GHz Step Attenuators

JFW is proud to announce the addition of a new line of 18 GHz step attenuators to our product line.  These new 50 Ohm solid-state step attenuators cover 100 MHz to 18 GHz with an attenuation range of 0-31 dB by 1dB steps.  The attenuators can handle up to +20 dBm of RF input power.  We offer these attenuators as individual components or as an integrated RF test system.

Introduction to JFW’s USB Attenuator Test Software

Why use a USB Attenuator?

In RF test labs, programmable attenuators and RF switches are a basic building block of performance testing. Programmable attenuators are used in fading, handover, and rate vs range testing. Among other things, RF switches are used in signal routing, component bypassing and switched filter banks. To fill this need, JFW offers an expansive selection of Programmable Attenuator Assemblies and RF Switch Assemblies in 19″ rack or benchtop enclosures. These boxes typically include Ethernet and RS-232 control. While appropriate for medium to large testing environments, a USB Attenuator or USB RF Switch is often a better solution for smaller test setups. Lower cost and smaller size of the USB device are especially relevant.
