An S-band CATT
Abstract
The experiments described were aimed at gaining better insight into the dynamics of controlled-avalanche transit-time triodes (CATT) developed to provide a practical three-terminal device for higher frequencies by using the additional gain available through avalanche multiplication of the collector current. A substantial gain advantage over transistors with comparable emitter-base geometry is demonstrated. This implies that CATT devices can be operated at significantly higher frequencies than transistors for a given fabrication technology. The absence of current injection limiting effects characteristic of transistors indicates that CATTs should have an advantage in peak power performance in short pulse operation. Many aspects of CATT devices will require further study before optimum devices and circuits can be designed.
