4.6 Output Power Programming

The RF output power of the CC2530 - CC2592EM is controlled by the 8-bit value in the CC2530 TXPOWER register. Table 6 shows the typical output power and current consumption for the recommended power settings. The results are given for TC = 25°C, VDD = 3.0 V and f = 2440 MHz, and are measured on the SimpleLink™ ZigBee® Network Range Extender Reference Design[3] with a 50 Ω load. For recommendations on the remaining CC2530 registers, see Section 8.

Table 6. Power Table

TXPOWER Power [dBm] Current [mA]
0xF5 21.1 172.3
0xE5 20.4 155.7
0xD5 19.7 143.1
0xC5 18.9 133.8
0xB5 18.2 124.8
0xA5 17.2 115.2
0x95 15.7 102.7
0x85 14.8 95
0x75 13.4 87.5
0x65 11.8 82.3
0x55 9.9 77.9
0x45 7.7 75.1
0x35 5.4 73.6

Note that the recommended power settings given in Table 6 are a subset of all the possible TXPOWER register settings. Using settings other than those recommended might result in sub-optimal performance in areas like current consumption, EVM, and spurious emission.
