Product Description
The L1FPDC is a one input, one output RF device that provides additional GPS L1 filtering from a GPS antenna. The frequency response covers L1 centered at 1575MHz. In the normal configuration, the RF output (J1) passes DC from the connected GPS receiver through the input port to the antenna, allowing the GPS receiver to power the antenna.
