GaN protection at any power up/power down sequence

GaN protection at any power up/power down sequence
A GaN bias controller and sequencer for fixed and pulsed negative gate biasing has been introduced by M/A-COM Technology Solutions. The MABC-001000-DP000L provides proper gate voltage and pulsed drain voltage biasing for a Device Under Test (DUT). The device also provides bias sequencing, ensuring that the pulsed drain voltage cannot be applied to a device under test unless the negative gate bias voltage is present.
