AP.25F.07.0078A Specification Part No. AP.25F.07.0078A Product Name 25mm Two Stage GPS Active Patch Antenna Module with front-end Saw Filter Feature Industry leading GPS antenna performance 25mm*25mm*8mm (Ground Plane) 78mm Ø1.13 I-PEX MHFI (U.FL) 28dB LNA Wide Input Voltage 1.8V to 5.5V Low Power Consumption ROHS Compliant SPE-11-8-030/A | page 1 of 11 1. Introduction The AP.25F 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.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 XtremeGainTM technology for the highest sensitivity in the industry. The AP.25F consists of 2 functional blocks – the LNA and also the patch antenna. ANTENNA SAW Filter LNA LNA I-PEX + cable 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 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 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. Coaxial Cable (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. 2 PLUG 1 Pulling Tool P/N : 90192-001 RECEPTACLE 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. 2N MAX.
