GPS Attenuators

GPS Attenuators

Available from APC Time, GNSS attenuators reduce the power and amplitude of the GPS signal with minimal distortion. All GPS Source attenuators are capable of passing DC bias voltage through the device or blocking the DC path, without affecting the GPS signal.

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.

  • Supports GPS, galileo and GLONASS – all bands
  • Ports pass DC voltage to the antenna
  • Excellent flat response
  • Reverse isolation greater than 50dB
  • MIL-STD-810 design

GPS Attenuator Mini Housing – AT11M

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.

  • Supports GPS, galileo and GLONASS – all bands
  • Ports pass DC voltage to the antenna
  • Excellent flat response
  • Reverse isolation greater than 50dB
  • MIL-STD-810 design
