DESCRIPTION:
The MS1455 is a 12.5 V Class C epitaxial silicon NPN planar
transistor designed for amplifier applications in the
806-866 MHz frequency range. Internal impedance matching
assures optimum gain and efficiency across the entire
frequency band. Gold metalization and emitter ballast resistors
assures infinite VSWR capability and long term reliability.
