Analog IP Cell UHF-Limiter and Modulator UHF-LIMMOD XH035 General Description The LIMMOD is an analog standard cell for UHF RFID applications. The cell consists of two parts. First section is a limiter that limits an input voltage to 3,4volt maximum level. Second section is a modulator which changes the electrical field of an antenna signal in an RFID tag chip. The limiter protects the following circuitry against higher input voltage, e.g. in close field proximity. The modulator attenuates the incoming antenna signal and has to be stimulated accordingly by a digital core. An RFID reader at the other end of the communication channel demodulates the received TAG signal. This cell can be used with minor changes for HF (13.56MHz) tag ICs as well.
