The LA20RPDC from GPS Networking is an active GPS low noise amplifier that operates from 1.1 to 1.7 GHz. It provides a gain of 20 dB, has a noise figure of 1.1 dB with 57 dB of reverse isolation. This amplifier requires a DC supply from 3.3 to 15 V and draws 18 mA of current. This voltage is regulated and used to power the internal amplifier while unregulated voltage is passed through the antenna port to power a connected active antenna or other upstream devices.
The LA20RPDC can accept all major GNSS constellation signals. It is available in a package with TNC female connectors (connector types can be customized). The amplifier is ideal for use as an in-line amplifier to negate the insertion loss of a long cable run, as a low-noise preamplifier for a passive GNSS antenna, as an amplifier in a re-radiating system, and in combination with one of a splitter, devices to create a GPS distribution network.
