GPSnetworking VGLA20RPDC 放大器

The VGLA20RPDC GPS Variable Gain Line Amplifier is a one input, one output device featuring a variable gain block with 26dB of dynamic range. The frequency response covers the GPS L1 & L2 bands with excellent flatness throughout most of the attenuation range. In the normal 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 antennathe amp. .
