ETSI EN 300 328 v 2.2.2, Ch 4.3.2.3 limits the power spectral density to 10 dBm/MHz for non-FHSS equipment. The Nordic Thingy:53™ conforms to this requirement when the nRF5340 TX output power and nRF21540 gain configurations are set according to the following protocol-specific channel maps.
Setting/Frequency | 2402–2480 MHz |
---|---|
nRF5340 TX output power | –5 dBm |
nRF21540 gain | 10 dB |
Conducted output power nRF21540 ANT1 PORT1 | 5.6 dBm (2402 MHz) 6.4 dBm (2440 MHz) 6.1 dBm (2480 MHz) |
Max. EIRP2 | 7.71 dBm (2402 MHz) 9.19 dBm (2440 MHz) 7.7 dBm (2480 MHz) |
Setting/Frequency | 2404–2478 MHz |
