GENERAL PURPOSE LINEAR APPLICATIONS
DESCRIPTION
The SD1855 is a silicon NPN planar transistor
designed for high gain linear performance at 2.0
GHz. This part uses gold metallized die and polysilicon site balla sting to achieve high rel iability and
ruggedness. The SD1855 can be used for applications suc ha as telecommu nicati ons, rada r, ECM,
space and other c ommer cial and militar y systems.
