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/GALILEO 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 sales@taoglas.com 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.
