Duty cycling
The current consumption of the BGT60LTR11AIP MMIC can be optimized by configuring the duty cycle Pulse
width (PW) and the Pulse Repetition Time (PRT). With the default PW of 5 µs, which means the time BGT is active
during one pulsing event, the current consumption values of the MMIC are listed in Table 9.
