New Wide Band Attenuator simplifies communication test.
The new 50P-1857 programmable attenuator from JFW Industries offers solid-state reliability and superior broadband performance. With an operating frequency range of 200 to 6000 MHz, it is ideal for today's wideband variable attenuator requirements including VHF/UHF, LTE and WiMAX testing applications.
This 50-Ohm device has a dynamic range of 0 to 95 dB in 1 dB steps and is guaranteed monotonic across its entire bandwidth. SMA female connectors are standard on the input and output, but other connector configurations may be available upon request.
