Patent Images
1. An amplifier system comprising:
- a high-frequency electromagnetic energy source;
a multistage cascade array of amplifying means including a plurality of electrically paralleled solid-state elements exhibiting negative resistance characteristics disposed within a plurality of resonant cavities;
the total number of said elements successively increasing in each successive resonant cavity;
circuit means interconnecting said source and each stage of said array in cascade to utilization means;
said circuit means including four-port circulator energy transmission means each interconnecting through impedance transformer means each of said resonant cavities; and
means for absorbing undesired reflected energy coupled to one port of each circulator means.

Abstract
A high-power solid-state amplifier system is disclosed having plural semiconductor amplifying elements electrically oriented in parallel in a multistage array. The number of elements in each stage successively increases with all elements operating at substantially the same RF voltage level. The stages are interconnected by circulator transmission means. Two modes of operation are permissible, namely, as a reflection-type amplifier or phase lock oscillator. Suggested amplifying elements include negative resistance semiconductors of the bulk effect or avalanche-type.
