The MABC-001000-DP000L is a bias controller that
provides proper gate voltage and pulsed drain
voltage biasing for a device under test (DUT).
Applicable DUT’s would be 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.

Ground
The applications section of this datasheet will show
how the module can be implemented for the
following two applications:
Drain (+) Supply Voltage
Driver Output to MOS Switch Gate
No Connect
Auxiliary +4.3 VDC Output
MOS Switch Enable TTL
Ground
Application Option 1: Fixed negative gate
biasing with pulsed drain biasing.
Application Option 2: Pulsed negative gate
biasing with pulsed drain biasing.
Ground
1. Unused package pins must be left open and not connected to
ground.
Ordering Information2
Both of these applications will recommend the
external circuitry and p-Channel Power MOSFET.
