Power transfer
Power transfer to the LRI64 is accomplished by inductive coupling of the 13.56 MHz radio
signal between the antennas of the LRI64 and VCD. The RF field transmitted by the VCD
induces an AC voltage on the LRI64 antenna, which is then rectified, smoothed and voltage-
regulated. Any amplitude modulation present on the signal is demodulated by the amplitude
shift keying (ASK) demodulator.
4.1
Frequency
ISO 15693 and ISO 18000-3 Mode 1 standards define the carrier frequency (fC) of the
operating field to be 13.56 MHz±7kHz.
4.2
Operating field
The LRI64 operates continuously between Hmin and Hmax.
●
The minimum operating field is Hmin and has a value of 150mA/m (rms).
●
The maximum operating field is Hmax and has a value of 5A/m (rms).
A VCD generates a field of at least Hmin and not exceeding Hmax in the operating volume.
