SPE-11-8-038/C | page 2 of 11 The AP.25E has been designed specifically for embedded (inside device) integration with GPS 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 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 XtremeGainTM technology for the highest sensitivity in the industry. The AP.25E consists of 2 functional blocks – the LNA and also the patch antenna. 1. Introduction ANTENNA SAW Filter LNA I-PEX + cable 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 antenna, it helps avoid burn-out of the LNA or the module due to interference from the GSM transmitter at out band frequencies.

Plugs Usage Precautions (1) To disconnect connectors, insert the end portion of I-PEX under the connector flanges and pull off vertically, in the direc- tion of the connector mating axis. (2) To mate the connectors, the mating axes of both connectors must be aligned and the connectors can be mated. The “click” will confirm fully mated connection. Do not attempt to insert on an extreme angle. After the connectors are mated, do not apply a load to the cable in excess of the values indicated in the diagram below.
