GPS Attenuators

The AT11 GPS Fixed Attenuator is a one input one output RF device. Designed specifically for use in all L-Band channels of Global Navigation Satellite Systems, including GPS, Galileo, GLONASS, and QZSS, the AT11 Fixed Attenuators provide a user specified attenuation from 2 to 40dB.

The AT11 also includes the option to pass the receive antenna LNA DC bias voltage through the device or to block the DC path to the antenna.

The most common application is taking the input level to a GPS receiver or a GPS test set is reduced via the fixed attenuation of the AT11. The AT11 is available with more options than any competitive product on the market.
