DESCRIPTION
The NE673 features a low noise figure and high associated
gain through K-band by employing a recessed 0.3 micron
gate and triple epitaxial technology for industrial and space
applications.
The device is available as a chip (NE67300). The chip's gate
and channel are glassivated with a thin layer of Si
