GPS Attenuator – AT11
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.
The AT11V GPS Variable Attenuator is a one input one output RF device. The most common use being the input level to a GPS receiver or a GPS test set is controlled via a potentiometer using an external knob. The AT11V is available with more options than any competitive product in the GPS Market.
Ports pass DC voltage to the antenna
50Ω impedance on both ports
Customer can choose to block DC to the antenna
Frequency response GPS L1/L2, Galileo, and GLONASS
The AT11M GPS Fixed Attenuator is a one input one output RF device in a small form factor. Designed specifically for use in all L-Band channels of global navigation satellite systems, including GPS, Galileo, GLONASS, and QZSS, the AT11M Fixed Attenuators provide a user-specified attenuation from 2 to 40dB. The AT11M also includes the option to pass the receive antenna LNA DC bias voltage through the device or to block the DCpath to the antenna. This is a passive non-powered version of the standard fixed attenuator.
The AT11T 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.
