DESCRIPTION
The AM81720-012 is designed specifically for Tele-
communications applications.
The device is capable of withstanding any mis-
match load condition at any phase angle (VSWR
:1) under full rated conditions. The unit is an
overlay, emitter site ballasted, geometry utilizing
a refractory/gold metallization system.
The unique AMPACTM devices are housed in Her-
metic Metal/Ceramic packages with internal
Input/Output matching structures.
