SPECIFICATION Part No. : AP.25M.07.0080A Product Name : 25mm One Stage GPS Active Patch Antenna Module with front-end Saw Filter Features : Industry leading GPS antenna performance 25*25*6mm 80mm Ø1.13 I-PEX MHFI (U.FL) 15dB LNA Wide Input Voltage 1.8V to 5.5V Low Power Consumption ROHS Compliant Photo : SPE-12-8-001/D/SS Page 1 of 14 1. Introduction The AP.25M is a one stage 25mm active patch antenna that has been designed specifically for embedded (inside device) integration with GPS receiver modules. The AP.25M 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. It comes with it’s own integrated ground-plane. The front end SAW filter reduces the risks where there is a cellular transmitter nearby of interference from out of band frequencies which can cause LNA burn-out, saturation, or radiated spurious emissions. The antenna can work on a wide input voltage from 1.8V to 5.5V with best in class power consumption figures. If further tuning and optimization specific to a customer device is required Taoglas offers a custom tuned and optimized part service. Contact [email protected] for more information.Cables and connectors can be customized according to request. This antenna system consists of two functional blocks, the LNA portion and the patch antenna. . SPE-12-8-001/D/SS Page 2 of 14 2.

Plugs Usage Precautions 8.1 Mating / unmating (1) To disconnect connectors, insert the end portion of I-PEX under the connector flanges and pull off vertically, in the direction 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. 8.2 Pull forces on the cable after connectors are mated After the connectors are mated, do not apply a load to the cable in excess of the values indicated in the diagram below.
