Margins for passing conducted requirements at the third harmonic can be improved by using a simple band-pass filter connected
between matching network and RF connector (1.8 pF in parallel with 1.6 nH); this filter must be connected to a good RF ground.

Margins for passing FCC requirements at 2483.5 MHz and above when transmitting at 2480 MHz can be improved by using a lower
output-power setting or having less than 100% duty cycle.
