Figure 1. 58536A GPS Distribution Amplifier
1.0 Introduction
The 58536A GPS distribution amplifier is one component of a complete line of GPS
accessories available from Symmetricom. These accessories are designed to deliver precise
GPS signals over a wide temperature range and in harsh environmental conditions.
The distribution amplifier is required if you wish to distribute the signal from a single
antenna to as many as four GPS receivers.
2.0 Description
The 58536A consists of a broadband, unity gain amplifier and a 1:4 signal splitter. Designed
for use with GPS antennas, the unit features a high degree of isolation to eliminate feedback
and interaction between any GPS systems connected to it.
Power to the unit is supplied by a GPS timing receiver connected to one of the four ports.
This means that the distribution amplifier will operate as long as there is at least one
working GPS receiver connected to any one of the distribution amplifier ports.
3.0 Use with Non-Symmetricom Systems
Although designed for use with Symmetricom GPS receivers, the 58536A can be used with
other GPS receiver and antenna systems.
The 58536A operates over a voltage range of
+
4.5 Vdc to
+
13 Vdc. Power from the GPS
receiver is passed through to the antenna.
