Frequency, f (GHz)

DESCRIPTION

NEC's NE856 series of NPN epitaxial silicon transistors is

designed for low cost amplifier and oscillator applications. Low

noise figures, high gain, and high current capability equate to

wide dynamic range and excellent linearity. The NE856 series

offers excellent performance and reliability at low cost. This is

achieved by NEC's titanium/platinum/gold metallization sys-

tem and their direct nitride passivated base surface process.

The NE856 series is available in chip form and a Micro-x

package for high frequency applications. It is also available in

several low cost plastic package styles.
