Product Description
The MAGX-000912-125L00 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 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) Operation of this device above any one of these parameters may cause permanent damage.
(2) Channel temperature directly affects a device's MTTF. Channel temperature should be kept as low as
possible to maximize lifetime.
(3) For saturated performance it recommended that the sum of (3*Vdd + abs(Vgg)) <175
