Abstract of the Disclosure

A distributed collector ballast resistor structure for use in a distributed collector contacted transistor comprises a diffusion geometry which is designed to employ a number of distributed collector ballast resistors in parallel as opposed to a single bulk resistor in a series with the collector circuit thereby generating a lower current for a given voltage during avalanche while allowing lower saturation voltage, better RF gain and higher saturated output power.
