DESC RIPT ION
The MSC81005 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 an infinite load VSWR at any phase angleunder rated rated conditions. The MSC81005 is designed for Class C amplifier ap­plications in the 0.4 - 1.2 GHz frequency range.
