AP12F070045A Datasheet, PDF (2/8 Pages) List of Unclassifed Manufacturers – 12mm Two Stage 25dB GPS Active Patch Antenna Module with front-end Saw Filter

1. Introduction
The AP.12F has been designed specifically for embedded (inside device) integration with
GPS/GALILEO receiver modules where there is a GSM transmitter nearby and risk of
interference and saturation.
The AP.12F combines a 12*12*3.5mm advanced low profile ceramic patch antenna with
a two stage LNA and a front-end SAW filter with ultra thin coaxial cable.
Only 5.6mm in height, this Taoglas active antenna module utilises XtremeGain™
technology for the highest industry sensitivity. The AP.12F consists of 2 functional blocks
– the LNA and also the patch antenna.
The AP.12F has a SAW filter on the front of it. The main use of the AP.12F would be for
small devices where the GSM transmitter is close to the GPS/GALILEO antenna, it helps
avoid burn-out of the LNA or the module due to interference from the GSM transmitter at
out band frequencies.
