1. Introduction
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.

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.

8. 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.
