MFRC500:
The matching circuit consists of an EMC low-pass filter (L0 and C0), matching circuitry
(C1 and C2), a receiver circuit (R1, R2, C3 and C4) and the antenna itself.
Refer to the following application notes for more detailed information about designing and
tuning an antenna.
The MIFARE system operates at a frequency of 13.56 MHz. This frequency is generated
by a quartz oscillator to clock the MFRC500. It is also the basis for driving the antenna
using the 13.56 MHz energy carrier. This not only causes power emissions at 13.56 MHz,
it also emits power at higher harmonics. International EMC regulations define the
amplitude of the emitted power over a broad frequency range. To meet these regulations,
appropriate filtering of the output signal is required.
