## **1. Introduction** 

The AP.25E 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.25E combines a 25*25*2mm advanced low profile ceramic patch antenna with a one stage LNA and a front-end SAW filter with ultra thin coaxial cable. 

The Ground Plane size of 35*35mm combined with the larger size GPS/GALILEO Patch,  gives this solution a performance increase in gain of 1 2dB. It also helps shields the patch antenna from noise and increases performance at low elevations. Taoglas active antenna modules utilise XtremeGain™ technology for the highest sensitivity in the industry. The AP.25E consists of 2 functional blocks – the LNA and also the patch antenna. 

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