ATTENPDC: GPS Fixed Attenuator

Overview

ATTENPDC GPS Fixed Attenuator

The XXATTENPDC GPS Fixed Attenuator (GNSS Attenuator) is a one input, one output device that can be specified with a fixed attenuation value 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.
