Product Description

The ALDCBS1X4 GPS amplified splitter has one input and four outputs and is based on the Wilkinson splitter design. The frequency response covers the entire L-band (GNSS) frequencies with excellent gain flatness. In normal configuration, the RF output (J1) passes DC from a connected GPS receiver through the splitter and onto the antenna. This allows the GPS receiver to power both the antenna and the splitters internal amplifier. Each RF output (J2-J4) are DC blocked and incorporates a 200 resistor to simulate the antenna current draw preventing false antenna alarm faults.

This ALDCBS1X4 GPS amplified splitter (EDMO# ALDCBS1X4S) includes one input and four outputs each with SMA connectors.
