描述：
The LA20FPDC GPS Filtered Line Amplifier is a one input, one output device with a 20dB min. gain block and L1/L2 filtering. The frequency response covers both GPS L1 & L2 bands. 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 amp.
