L1/L2FPDC GPS Filter

GPS Networking – L1/L2FPDC L1/L2 GPS Filter (Pass DC)

Manufacturer: | Categories: ,

The L1L2FPDC from GPS Networking is a GPS passband filter designed specifically for the GPS L1 and L2 carrier frequencies. The L1L2FPDC lowers the out of band noise and interference by 20dB. The DC voltage is then passed to the intended GPS antenna or source. All filters are available with N-type, SMA, BNC or TNC connectors.



The L1/L2FPDC is a one input, one output RF device which provides additional GPS L1 and L2 filtering. The frequency response covers both L1 and L2 with low insertion loss. 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.
