JFW Attenuators

  1. Bench Top Rotary Attenuator: 75BR-023 2/2/2016

    The 75BR-023 from JFW is a benchtop rotary attenuator for applications in the DC to 2150 MHz frequency range. This attenuator is one of the passive 75 Ohms nominal impedance components, and features an attenuation range of 0-70 dB in 1 dB increments, which increases in a counter-clockwise direction.

  2. Multiple Programmable Attenuator System: 75PA-076 2/2/2016

    JFW’s 75PA-076 is a multiple programmable attenuator system with two individually controlled electro-mechanical programmable attenuators. Featuring an attenuation range of 0 to 63 dB in 1 dB increments and 75 Ohms nominal impedance, the system is perfect for applications in the DC-2150 MHz range.

  3. Ethernet-Controlled Attenuation Systems: 50PA Series 8/11/2015

    JFW presents a new line of programmable, Ethernet-controlled attenuator assemblies. These RF attenuation systems are available in frequencies as low as 30 MHz or up to 6 GHz, in 95 dB, 63 dB, or 127 dB of dynamic range (in 1 dB steps), and with SMA or N connectors. They are housed in 19” rack mountable enclosures, and have 50 Ohms of impedance.

    All models are guaranteed to be shipped within four weeks or less!

  4. Solid State USB Programmable Attenuator: 50P-2014 11/7/2014

    JFW’s 50P-2014 is a programmable attenuator designed with USB control, making it ideal for R&D labs or other flexible test environments. It covers the 200-6000 MHz frequency range, and it has a 0-95dB attenuation range (in 1dB steps).

  5. DC - 2700MHz Manually Variable Attenuator: 50DR-125 4/14/2011

    JFW is proud to present our latest manually variable attenuator that makes attenuation fading of LTE products quick and easy.

  6. Programmable Attenuator: 50P-1857 SMA 2/8/2010

    The new 50P-1857 SMA, programmable attenuator, offers solid-state reliability and speed as well as superior broadband performance (200-6000 MHz). It has a dynamic range of 0-95dB in 1dB steps and is guaranteed monotonic across the band. TTL control and SMA female connectors are standard, but other control and connector configurations are also available.
