Description:
These SSM devices are epitaxial silicon NPN-planar transistors designed primarily for 12.5 volt AM class C rf amplifiers functional in the aviation band 118-136 MHz and for 28V FM class C rf amplifers utilized in ground station transmitters. These devices utilize ballasted emitter resistors and improved metalization systems to achieve optimum load mismatch capability.
