TK5552
4698A–RFID–04/03
Operating Distance
The maximum distance between the base station and the TK5552 depends mainly on
the base station, the coil geometries and the modulation options chosen (see “U2270B
Antenna Design Hints” application note and the “U2270B” datasheet). When using
Atmel’s U2270B demo board, typical distances in the range of 0 to 5 cm can be
achieved. Maximum distance values which are generally valid can not be given in this
datasheet. The exact measurement of the maximum distance should be carried out with
the TK5552 being integrated into the specific application.
For longer distances used in industrial applications, please use specific solutions like
two or more reader coils.
