There is the potential for 24MHz harmonics radiating from pins 22 through 28 of the
ThingMagic Nano. If emissions testing shows such harmonics, the easiest fix is to
put bypass capacitors (typically 39 to 100pf) directly at the offending pins on the
carrier board. Note that higher values are not necessarily better. The ideal capacitor
value will have series resonance near the most offending frequency. 39pF has been
good for around 900 MHz in sample board layouts.
