The XXATTENPDC fixed GPS attenuator is a one input and one output device that allows DC voltage to pass from the J1 port through the antenna port to provide power to an active antenna. This unit is designed to cover all major GNSS constellations with excellent gain flatness. The unregulated voltage that is passed through can power other upstream device including active antennas.
This DC pass-thru fixed GPS attenuator (Alternate Part# 12ATTENPDC) will lessen GPS signal 12 dB and has N-type connectors.
- Custom attenuation level fixed up to 30 dB
- Compact form factor
- Extremely flat group delay: <1 ns variation
- Excellent flatness: <1 dB attenuation between L1 & L1
- Low SWR: < 2.0:1 maximum
