TX current (SISO20)MCS7, 2.4GHz, +11.2 dBm238mA
Maximum peak current consumption during calibration(2)850mA
(1) The system design power scheme must comply with both peak and average TX bursts.
(2) Peak current VBAT can hit 850mA during device calibration.
  • At wakeup, the WiLink 8 module performs the entire calibration sequence at the center of the 2.4GHz band.
  • After a link is established, calibration is performed periodically (every 5 minutes) on the specific channel tuned.
  • The maximum VBAT value is based on peak calibration consumption with a 30% margin.
