Abstract: A triode having a coaxially positioned cathode and grid or gate electrode positioned within an evacuated tubular anode. The cathode has a plurality of emitting points radially disposed on its outer surface. The emitting points are surrounded by a plurality of grid or gate electrodes controlling the conducted beam current between the inner cathode and the surrounding anode. The gain and power of the triode is only limited by the number of emitter points and the number of grid or gate electrodes positioned within the anode. Since the anode envelopes the cathode and grid electrode, the anode can be used as a waveguide or antenna launch without the need of RF coupling connectors.

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.
