Introduction** The AP.35A has been designed for embedded (inside device) integration with GPS receiver modules, the AP.35A combines a 35*35*3.5mm advanced low profile ceramic patch antenna with a one stage LNA and ultra thin coaxial cable. The Ground Plane size of 35*35mm combined with the larger size GPS 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. This antenna system consists of two functional blocks, the LNA portion and the patch antenna. The AP.35A has a back-end SAW filter. Page 2 of 11 SPE-12-8-023/D/SS ## **2. Specification** ## **2.1.
