MICROWAVE LOW NOISE AMPLIFIER
NPN SILICON EPITAXIAL TRANSISOR
DESCRIPTION
PACKAGE DIMENSIONS
The 2SC3585 is an NPN epitaxial silicon transistor designed for use in
low-noise and small signal amplifiers from VHF band to UHF band. The
2SC3585 features excellent power gain with very low-noise figures. The
2SC3585 employs direct nitride passivated base surface process (DNP
process) which is an NEC proprietary new fabrication technique which
provides excellent noise figures at high current values. This allows
excellent associated gain and very wide dynamic range.
