  • Amplifier Gain: 20dB typical
  • Passes L1/L2  GPS, Galileo & BEIDOU
  • High Rejection outside L1 and L2 


This Line Amplifier 20dB Filtered Pass DC (LA20FPDC) is an active one input, one output amplifier optimized for GPS applications. This equipment accepts signals covering all major GNSS constellations with excellent gain flatness and a very low noise figure. In the standard configuration, the J1 port accepts DC voltage from a connected GPS receiver. This voltage is regulated and used to power the internal amplifiers while unregulated voltage is passed through the antenna port to power a connected active antenna or other upstream devices. The frequency response covers both GPS L1 & L2 bands in addition to passing GNSS frequencies. There is greater than 20dB rejection minimum +/- 100MHz relative to the passband. In the standard configuration, the RF output (J1) passes DC from the connected GPS receiver through the amplifier to the antenna, allowing the GPS receiver to power both the antenna and the amplifier. Custom gain between 3-25dB may be ordered as well. Please contact GPS Networking Technical Support for any questions regarding the standard or special configurations at or
