DESCRIPTION
NEC's NE681 series of NPN epitaxial silicon transistors are
designed for low noise, high gain, low cost amplifier applica-
tions. Both the chip and micro-x versions are suitable for
amplifier applications up to 4 GHz. The NE681 die is also
available in six different low cost plastic surface mount pack-
age styles. NE681's unique device characteristics allow you to
use a single matching point to simultaneously achieve both low
noise and high gain.
