DESCRIPTION
The MSC81005 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
MSC81005 is designed for Class C amplifier ap-
plications in the 0.4 - 1.2 GHz frequency range.
