NPN silicon planar epitaxial transistors, intended for wideband applications in the GHz range, such as analog and digital cellular telephones, cordless telephones (CT1, CT2, DECT, etc.), radar detectors, satellite TV tuners (SATV), MATV/CATV amplifiers, and repeater amplifiers in fiber-optical systems. The transistors are mounted in plastic SOT143B and SOT143R packages.
