DESC RIPT ION
The MSC81058 is a common base hermetically
sealed silicon NPN microwave transistor utilizing
a fishbone, emitter ballasted geometry with a refractory/gold metallization system. This device is
capable of withstanding infinite load VSWR at any
phase angle under rated conditions.
The MSC81058 is designed for Class C amplifier
applications in the 0.4 - 1.2 GHz frequency range.
