Measurement conducted with 100 kHz resolution bandwidth on
spectrum analyzer. Output Delivered to a single ended 50 ? load
through a balun.
Maximum output power.
Texas Instruments CC2480 EM reference design complies with
EN 300 328, EN 300 440, FCC CFR47 Part 15 and ARIB STD-
T-66.
Transmit on 2480MHz under FCC is supported by duty-cycling
The peak conducted spurious emission is -47 dBm @ 192 MHz
which is in an EN 300 440 restricted band limited to -54 dBm. All
radiated spurious emissions are within the limits of
ETSI/FCC/ARIB. Conducted spurious emission (CSE) can be
reduced with a simple band pass filter connected between
matching network and RF connector (1.8 pF in parallel with 1.6
nH reduces the CSE by 20 dB), this filter must be connected to
good RF ground.
