Product Description
The LA20RPDC is a one input, one output Low Noise Amplifier with 20dB gain typical. The frequency response covers GPS L1, L2, L5, Galileo, GLONASS and all other L-band frequencies with excellent flatness. In the default configuration, the RF output (J1) passes DC from the connected GPS receiver through the amplifier to the active antenna, allowing the GPS receiver to power both the antenna and the LA20RPDC amplifier. In the Networked (Externally Powered) configuration, the output is DC Blocked and the user selects the input voltage that will be sent up the coax to power an external antenna. The LA20RPDC has a very low noise figure and an excellent 1dB compression point.
LA20RPDC-N has N-type connectors
