AT11V ATTENUATORFeatures
 Excellent Flat Response Pass DC or DC Block Passes GPS, Galileo & GLONASS L1/L2
 0dB to 40dB Variable Gain

Description
Designed with the thin link margins of satellite navigation systems in mind, the AT11V Attenuator covers the GPS, Galileo, and
GLONASS frequencies. The AT11V GPS Variable Attenuator is a one input one output RF device. The most common use is tovary the input level to a GPS receiver or a GPS test set controlled via a potentiometer with an external knob. AT11V Variable
Attenuator provides a range of attenuation from 0 to 40dB. The AT11V 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 AT11V attenuator comes with many available options to meet your specific needs. Please call, fax, email(sales@gpssource.com), or visit our website (www.gpssource.com) for further information on product options & specifications.

Notes:
1. DC IN for powered option must be 2V greater than desired DC Voltage Out
2. Maximum combined DC current draw out all ports of the device is a function of the DC input voltage and desired DC output
voltage , according to the following:
Iout ≤ 1.4 / (VDC IN - VDC OUT ) - 0.007 Amps
For powered option with a wall mount transformer (Voltage Input = 110/220/240
VAC), VDC IN is 9V.
3. The SWR specification is not met for attenuation greater than 30dB.
