Texas Instruments CC2530 EM reference design is suitable for systems targeting compliance with EN 300 328, EN 300 440, FCC

CFR47 Part 15, and ARIB STD-T-66.

(2)

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.

(3)

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.
