power Typical value Unit
IRF 250Kbps +18dBm 140 mA
IRF 250Kbps +13dBm 55 mA
IRF 250Kbps +10dBm 41.5 mA
IRF 250Kbps +0dBm 21 mA
Note: When the above data are tested, constant transmission is required, that
is, duty cycle=100%.
3.4 Zigbee RX power consumption
Symbol Rate Typical value Unit
IRF 250Kbps 8 mA
Note: When the UART is in active state, the receiving current is 14mA.
