COMMON BASE CONFIGURATION
DESCRIPTION:
The MS2267 is a high power Class C NPN transistor
specifically designed for TACAN/DME applications.
This device is capable of operation under moderate pulse
width and duty cycles. Low thermal resistance and
computerized automatic wire bonding techniques ensure
high reliability and product consistency.
The MS2267 utilizes an emitter ballasted die geometry
capable of operating into a 5:1 VSWR @ 1.0 dB overdrive.
