Note 1:
amplitude of the 2kHz- modulation, generated by the
transponder, demodulated and decoded by the reader.
This parameter depends on the application:
Note 2: The antenna amplitude voltage is:
Vant = V
Note 3: The supply current of the device depends on the
antenna drive current I
Typically: I
Note 4: The antenna supply current (called I
equivalent DC supply current driven by the chip through
the antenna.
