Product Description

This amplified GPS RF splitter designed for military applications and capable of covering all of the L1 and L2 GPS frequency bands as well as major GNSS constellations from 1.1 GHz to 1.7 GHz. It features one input and four outputs with excellent amplitude balance, flat group delay, and a high output gain across operating frequencies. It is design to amplify and distribute GPS signals from a single antenna to multiple devices. In the standard configuration, the J1 port passes DC voltage to the antenna or other devices; the other port J2 – J4 are DC blocked and loaded with 200Ω resisters to simulate current draw and prevent alarm faults. All mil-spec splitters are qualified to rigorous MIL-STD 810F environmental & MIL-STD-461F EMI standards.

This GPS RF splitter (EDMO# MILNALDCBB) features network power option, BNC connection, 5V output voltage, and a Military DC connector.

Features

Precise amplitude balance at less than 1dB between ports
Flat group delay less than 1ns variation between ports
High output gain at 18.5dB across all operating frequencies
Wide accepted frequency range covering entire L-band and major GNSS constellations
Efficiently block ports using 200Ω resisters eliminating alarm faults
Matched phase balance: less than 4° variation between ports
