DESCRIPTION
The MSC82005 is a common base hermetically
sealed silicon NPN microwave transistor utilizing
a fishbone emitter ballasted geometry with a re-
fractory/gold metallization system. This device is
capable of withstanding an infinite load VSWR at
any phase angle under rated rated conditions. The
MSC82005 was designed for Class C amplifier
applications in the 1.0 - 2.0 GHz frequency range.
