Product Description
The MAGX-000912-250L00 is a gold metalized matched
Gallium Nitride (GaN) on Silicon Carbide RF power transistor
optimized for civilian and military pulsed avionics amplifier
applications the 960 MHz to 1215 MHz range such as ModeS, TCAS, JTIDS, DME and TACAN . Using state of the art
wafer fabrication processes, these high performance
transistors provide high gain, efficiency, bandwidth,
ruggedness over a wide bandwidth for today’s demanding
application needs. High breakdown voltages allow for reliable
and stable operation in extreme mismatched load conditions
unparalleled with older semiconductor technologies.

TURNING THE DEVICE ON
TURNING THE DEVICE OFF
1. Set VGS to the pinch-off (VP), typically -5V
2. Turn on VDS to nominal voltage (50V)
3. Increase VGS until the IDS current is reached
4. Apply RF power to desired level
1. Turn the RF power off
2. Decrease VGS down to VP
3. Decrease VDS down to 0V
4. Turn off VGS
