Passive Military GPS Splitter | 1 Input, 4 Output, TNC Connectors
Product Description
The MIL-LDCBS1X4 military GPS splitter is a passive one input, four output RF splitter that splits signals from 1.1 GHz to 1.7 GHz. This equipment is designed to passively split signals within the L-band to provide multiple devices with the signal from a single antenna. In the standard configuration, the J1 port will pass DC voltage from a connected device and pass this power to the antenna or other devices upline from the splitter. The other ports (J2-J4) are DC blocked and loaded with 200Ω resistors to simulate antenna current draw which prevents antenna alarm faults. All MIL-Spec splitters are qualified to the rigorous MIL-STD 810F environmental & MILSTD-461F EMI standards.
This mil-spec GPS splitter (EDMO# MILLDCBS4T) features one input, four outputs, and has TNC-type connectors.
Features
- Precise Amplitude Balance: Less than 1 dB variation between ports
- Flat Group Delay: Less than 1ns variation between L1 and L2
- Low Insertion Loss: -7.5dB loss is typical across all operating frequencies
- Wide Accepted Frequency Range: Accepts signals from the entire L-Band, covering all major GNSS constellations
- Efficiently Blocked Ports: Uses 200Ω resistors to prevent antenna alarm faults from connected devices
- Matched Phase Balance: Less than 2° of variation between ports
