MS1509
DESCRIPTION:DESCRIPTION:
The MS1509 is a 28 V gold metallized, Class C epitaxial silicon
NPN planar transistor designed for UHF military and commercial
equipment. The MS1508 is an internally matched, broadband
device optimized for operation within the 100 – 500 MHz fre-
quency range. This device utilizes diffused emitter resistors
to achieve 5:1 VSWR load mismatch capability at rated
operating conditions.
