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.

USB Programmable Attenuators to 3 GHz w/ 0.25 & 0.5 dB steps

USB Programmable Attenuators

Now available from JFW:  USB Programmable Attenuators with 0.25 dB & 0.5 dB step size up to 3 GHz. The majority of programmable attenuators available have 1 dB steps.  However, for some applications, such as satellite communication testing, smaller step sizes can be beneficial.  For those cases, these three models can provide that capability.

New Models

  • 50P-2058 has 0.25 dB steps up to 31.75 dB.
  • 50P-2042 has 0.5 dB steps to 63.5 dB.
  • 50P-2055 goes all the way to 95.5 dB in 0.5 dB steps.

All three attenuators are controlled and powered through a Mini-B USB connector.  A USB hub can be used to simultaneously control multiple attenuators.  Included with each step attenuator is our Windows-based GUI software for easy attenuation control of a single or multiple attenuators.

Dual Rotary Attenuator for LTE Band 42 Testing

Dual Rotary Attenuator

JFW is excited to announce a new dual rotary attenuator, 50DR-141, that covers LTE Band 42. It functions from DC up to 3600 MHz. This attenuator handles up to 2 Watts of RF power. The maximum attenuation is 40 dB in 1 dB increments. The 50DR-141 has mounting holes in the front plate for easy mounting on panels for instrumentation applications. RF connector options include SMA or N.

In addition, the 50DR-141 can also be configured on 19″ Rack Panels, L-Brackets or Benchtop enclosures for use in test racks or lab environments.
