Description
The MAGX-000912-500L00 is a gold metalized
matched Gallium Nitride (GaN) on Silicon Carbide
RF power transistor optimized for civilian and military
pulsed avionics amplifier applications for the
960 MHz to 1215 MHz range such as Mode-S,
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.

1. Exceeding any one or combination of these limits may cause permanent damage to this device.
2. MACOM does not recommend sustained operation near these survivability limits.
3. For saturated performance it is recommended that the sum of ( 3 * VDD + | VGG | ) < 175 V.
4. Input Power Limit is +3 dB over nominal drive required to achieve P OUT = 125 W.
5. Operating junction temperature is measured with infrared (IR) microscope. Junction temperature directly affects a device's MTTF and
should be kept as low as possible to maximize lifetime.
MTTF = 5.3 x 106 hours (TJ < 200 °C)
MTTF = 6.8 x 104 hours (TJ < 250 °C)

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