GPS Networking – VATTENDCB GPS Variable Attenuator Blocks DC Voltage

Manufacturer: | Categories: ,

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



The VATTENDCB GPS RF Active Variable Attenuator is a one input, one output device with variable attenuation range from 0dB to 20dB, user selected pot range control. The device is available in a miniaturized housing.

The frequency response covers the GPS L1/L2 and GLONASS bands with excellent flatness. In the DC Blocked configuration, the RF output (J1) will pass DC from the connected GPS receiver to power the active variable attenuator and then block the DC at the input of the attenuator going to the antenna.
