GPS Networking – VATTENPDC GPS Variable Attenuator

Manufacturer: | Categories: ,

The VATTENPDC GPS attenuator from GPS Networking is designed specifically for the GPS L1, L2 and GLONASS carrier frequencies.



The VATTENPDC GPS Fixed Attenuator (GNSS Attenuator) is a one input, one output device that operates with a variable attenuation range that can be user selected between 0 – 20dB in a miniaturized housing. The frequency response covers the GPS L1, L2, L5, Galileo and GLONASS frequencies (entire L-band) with excellent flatness.

In the normal configuration, the RF output (J1) passes DC from the connected GPS receiver through the amplifier to the antenna, allowing the GPS receiver to power both the antenna and the mini amplifier.
