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 poly-

silicon site ballasting to achieve high reliability and

ruggedness. The SD1855 can be used for appli-

cations sucha as telecommunications, radar, ECM,

space and other commercial and military systems.
