DESCRIPTION
b e r sNEC's NE688 series of NPN epitaxial silicon transistors are
designed for low cost amplifier and oscillator applications. Low
P L E A S E N O T E : p a r t n u m n o tnoise figures, high gain and high current capability equate to
wide dynamic range and excellent linearity. NE688's low
T h e f o l l o wdi nagt a s h e e t a r ed e s i g n .phase noise distortion and high fT make it an excellent choice
for oscillator applications up to 5 GHz. The NE688 series is
available in six different low cost plastic surface mount pack-
t h i s f o r n e wage styles, and in chip form.
