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.
