This amplified loaded DC blocked GPS splitter features one input and two output for spitting RF frequencies from 1.1 GHz — 1.7 GHz. It is designed to amplify and split the L-band frequency to multiple devices from a single antenna. In the standard configuration, the J1 port passes DC voltage from a connected device to the antenna or another device up from the splitter. The other port J2 is DC blocked and loaded with a 200Ω resistor to simulate antenna current draw which prevent alarm faults.
This amplified GPS splitter (Alternate Part# ALDCBS1X2) features one input and two outputs, N-type female connectors.
- Excellent amplitude balance: < 1 dB variation between ports
- Flat group delay < 1 ns variation between L1 & L2
- High output gain: 22 dB typical across operating frequencies
- Wide accepted frequency range: entire L-band & major GNSS constellations
- Efficiently block ports: 200Ω prevents antenna alarm faults
- Matched phase balance: < 4° variation between ports
