DESCRIPTION: DESCRIPTION:
The MS1451 is a gold metallized silicon NPN planar transistor
designed for high linearity Class AB operation in cellular
base station applications. The MS1451 is designed as a
medium power output device or as the driver for MS1452.
Diffused emitter ballast resistors provide thermal stability
and reliability under Class AB linear operation.
