Description
DATASHEET : AT11M Technical Overview
GPS Source’s AT11M Fixed GPS Attenuator is a compact RF one input and one output unit. It is conceived especially for use in Global Navigation Satellite Systems, including every L-Band channel of Galileo, GLONASS, GPS, and QZSS. Attenuation ranges from 2 to 40 dB.
It can optionally pass LNA DC bias voltage to the receive antenna through the unit or block the DC path leading to the antenna. It is a non-powered, passive alternative to the standard fixed attenuator.
The AT11M is available with many connector, housing, and port options to meet a customer’s specific needs.
Features
