Fig 27.  Default 65x65 antenna matching diagram – symmetrical 

 

The antenna connection uses the standard tuning circuit Fig 10. The EMC filter is 
typically a second order low pass filter as shown in Fig 18, and contains an inductor (L0) 
and a capacitor (C0). The cut off frequency defines the overall detuning behavior as well 
as the transfer function of the antenna circuit. For symmetrical (DPC) tuning, EMC filter is 
designed with a cut off frequency of f

EMC

 = 14,8 MHz, and the antenna impedance is 

tuned to Z = 20Ω.
