CC2520 DATASHEET
2.4 GHZ IEEE 802.15.4/ZIGBEE® RF TRANSCEIVER
SWRS068 – DECEMBER 2007
PARAMETER
CONDITIONS
Largest spurious
emission at maximum
output power.
Texas Instruments CC2520
EM reference design
complies with EN 300 328,
EN 300 440, FCC CFR47
Part 15 and ARIB STDT-66.
25 MHz – 1 GHz (outside restricted bands)
25 MHz – 1 GHz (within FCC restricted bands)
47-74, 87.5-118, 174-230, 470-862 MHz (ETSI restricted bands)
Transmit on 2480 MHz
under FCC at +5 dBm is
supported by duty-cycling,
or by reducing output
power.
The peak conducted
spurious emission might
violate ETSI and FCC
restricted band limits at
frequencies below 1GHz.
All radiated spurious
emissions are within the
limits of ETSI/FCC/ARIB.
Applications that must pass
conducted requirements
are suggested to use a
simple 50 Ω high pass filter
between matching network
and RF connector.
1800 MHz-1900 MHz (ETSI restricted band)
5150 MHz-5300 MHz (ETSI restricted band)
At 2483.5 MHz and above (FCC restricted band)
f_c=2480 MHz, +5 dBm
f_c=2480 MHz, 0 dBm
At 2·RF and 3·RF (FCC restricted band)
Error Vector Magnitude
(EVM)
[2] requires max. 35%. Measured as defined by [2].
+5 dBm setting. f_c =IEEE 802.15.4 channels
0 dBm setting. f_c =IEEE 802.15.4 channels
