  • RF power bipolar junction transistor having performance-enhancing emitter structure
    Publication number: 20020070425
    Abstract: Performance of an RF power bipolar transistor having a collector region, at least one base region, and a plurality of elongated emitter fingers in each major region, is enhanced by forming each emitter finger with at least two spaced segments and contacting the two spaced segments with a metal lead. By eliminating the middle portion of each emitter finger, current hogging at the central portion and hot spot generation are eliminated. Power output is maintained with reduced emitter lengths by minimizing the adverse affects of the hot spot generation in the emitters.
