Description
The MAGX-003135-120L00 is a gold metalized
matched Gallium Nitride (GaN) on Silicon Carbide
RF power transistor optimized for civilian and military
radar pulsed applications between 3.1 - 3.5 GHz.
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.
The MAGX-003135-120L00 is constructed using a
thermally enhanced Cu/Mo/Cu flanged ceramic
package which provides excellent thermal
performance. High breakdown voltages allow for
reliable and stable operation in extreme mismatched
load conditions unparalleled with older
semiconductor technologies.
