Description
This loaded DC blocked passive splitter features one input and two outputs for splitting gps RF signals from 1.1 GHz to 1.7 GHz. This splitter is designed to deliver GPS signals within the L1 frequency band to multiple devices from a single antenna. In the standard configuration, the J1 port passes DC voltage from a connected device up to supply power to the antenna or other up device. The other ports (J2—J4) are DC blocked and loaded with a 200Ω resistor which simulates antenna draw to prevent alarm faults.
Features
- Precise amplitude balance: <1 dB variation between ports
- Flat group delay: <1 ns variation between L1 & L2
- Low insertion loss: -4.0 dB loss typical across operating frequencies
- Wide accepted frequency range: cover entire L-band & major GNSS constellations
- Efficiently block ports: 200Ω resistors prevent antenna alarm faults
- Matched phase balance: 2° variation between ports
