ABSTRACT:
A distributed array of microelectronic triodes constitutes a series of banks of triodes arranged in a concentric configuration. Each triode in the bank is a microelectronic triode fabricated by semiconductor integrated circuit techniques. Triodes in each individual bank are arranged in a parallel or other configuration whereby each of the triodes operate to provide increased power in regard to input signals applied to each bank. The array of triodes is capacitively coupled so that each of the banks contributes to the total output power. The coupling is provided for by capacitive coupling with biasing being accommodated by resistor biasing networks which are also integrated circuit components. The output power from the array is taken through a common output coupling configuration which configuration is connected to a suitable cylindrical member which operates to respond to the total output power of the array to enable the output power to be utilized in other suitable microwave components such as a coaxial line or a waveguide.
