DESCRIPTION
The AM1517-012 power transistor is designed spe- cifically for Satellite communications applications in the 1.5− 1.7 GHz frequency range. 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 AM1517-012 is supplied in the AMPAC Her- metic/Ceramic package with internal Input/Output matching structures.
