(1)

Texas Instruments CC2538 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)

To improve margins for passing FCC requirements at 2483.5 MHz and above when transmitting at 2480 MHz, use a lower output-power

setting or less than 100% duty cycle.
