RECOMMENDED BIAS SEQUENCING
Correct sequencing of the DC and RF power is required to safely
operate the ADL8124. To power up the ADL8124, take the following
bias sequencing steps:
1. Set VDD to 3.3V.
2. Set VENBL to VDD.
3. Apply the RF input signal.
The ideal power-down sequence is the reverse order of the power-
up sequence. Table 12 , Table 13 , Table 14, and Table 15 show
alternate bias resistor options for different VDD and IDQ choices.
