RF TRANSMIT SECTION
Measured on Texas Instruments CC2530 EM reference design with T_A = 25°C, VDD = 3 V and f_c = 2440 MHz, unless
otherwise noted.
Boldface limits apply over the entire operating range, T_A = –40°C to 125°C, VDD = 2 V to 3.6 V and f_c = 2394 MHz to 2507
MHz.

(1) 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.
