This GPS signal attenuator is a one input and one output device for reducing the signal strength by a fixed amount for optimizing GPS networks for specific applications. It will accept signals from all major GNSS constellations with excellent gain flatness. In the Standard configuration, port J1 will accept DC voltage from a GPS receiver while unregulated voltage is passed through the antenna port to provide power to an active antenna or other connected device.
This GPS line attenuator (Alternate Part# XXATTENPDC) lessens GPS signals by a fixed 20 dB and will pass DC voltage through the device to power upstream devices.
- Attenuates GPS signal by 20 dB
- Compact and lightweight
- Extremely flat group delay: <1 ns variation
- Excellent Flatness: attenuation on L1 & L2 bands < 1.0 dB
- Low SWR: < 2.0:1, max.
