Product Detail

GaN Bias Controller/Sequencer Module
The MABC-001000-DPS00L is a Low Power Dissipation bias controller that provides proper gate voltage and pulsed drain voltage biasing for a device under test (DUT). Applicable DUT’s include depletion-mode GaN (Gallium Nitride) or GaAs (Gallium Arsenide) power amplifiers or HEMT devices. The module also provides bias sequencing so that pulsed drain voltage cannot be applied to a DUT unless the negative gate bias voltage is present. The applications section of this datasheet will show how the module can be implemented for the following two applications: Application Option 1: Fixed negative gate biasing with pulsed drain biasing. Application Option 2: Pulsed negative gate biasing with pulsed drain biasing. Both of these application options will recommend the external circuitry and p-Channel Power MOSFET. The MABC-001000-DP000L module can also be installed onto an MABC-001000-PB2PPR evaluation board for evaluation, test, and characterization purposes.
