描述：
The LA20RPDC is a one input, one output device with a nominal 20dB gain block. The
frequency response covers Galileo, GLONASS and the L1, L2, L5 GPS bands 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.
