The NE687 series of NPN epitaxial silicon transistors are
designed for low cost, low noise applications. Excellent perfor-
mance at low voltage/low current makes this series an ideal
choice for portable wireless applications at 1.6, 1.9 and 2.4
GHz. The NE687 die is available in six different low cost plastic
surface mount package styles.
