## **1. Introduction** 

The AP.25F 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.25F combines a 25*25*4mm advanced low profile ceramic patch antenna with a two stage LNA and a front-end SAW filter, with ultra thin coaxial cable. 

Taoglas active antenna modules utilise XtremeGain™ technology for the highest sensitivity in the industry. The AP.25F consists of 2 functional blocks – the LNA and also the patch antenna. 

The AP.25F has a SAW filter on the front of it. The main use of the AP.25F 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.
