TECHNICAL PRODUCT DATA SHEET

A11Amplifier

DESCRIPTION
The A11 Amplifier is a single stage gain block which
covers the GPS, Galileo, and GLONASS frequencies.
It has been designed with the thin link margins ofsatellite navigation systems in mind.
The A11 features 30dB of gain, and a noise figure ofless than 1.8dB. It can be powered externally with an
AC input voltage option, a DC input option, or, since
the product consumes less than 16mA, it may be
powered by the GPS receiver’s in-line antenna voltage.
Regardless of the input power configuration, the A11
can provide a DC voltage output to power an active
GPS antenna.

FEATURES
Excellent Noise Figure: F < 1.8dB
 Excellent Gain: G = 30dB
 Passes GPS L1/L2/L5 and GNSS frequencies
 Variable Gain Option Available: 0dB to 30dB
OPTIONS
The A11 Amplifier can be custom configured. Pleasecontact GPS Source for further information on productoptions and specifications.
