1. Introduction
The AP.25E has been designed specifically for embedded (inside device) integration with
GPS/GALILEO 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/GALILEO Patch,
gives this solution a performance increase in gain of 12dB. 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.
The
AP.25E consists of 2 functional blocks
–
the LNA and also the patch antenna.
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/GALILEO antenna, it helps
avoid burn-out of the LNA or the module due to interference from the GSM transmitter at
out band frequencies.
