VGLA20RPDC-S, Variable Gain

US$600.00

Product Description

The VGLA20RPDC GPS Variable Gain Line Amplifier is a one input, one output device featuring a variable gain block with 25dB of dynamic range. The frequency response covers the GPS L1/L2 and GLONASS 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 antenna and the amplifier.
