1Power Vacuum Tube Applications

1.1 Introduction

The continuing demand for energy control devices capable of higher operating power, higher maximum frequency, greater efficiency, and extended reliability has pushed power vacuum tube manufacturers to break established performance barriers. Advancements in tube design and construction have given engineers new radio frequency (RF) generating systems that allow industry to grow and prosper. Power grid vacuum tubes have been the mainstay of high-power transmitters and other RF generation systems since the beginning of radio. Today, the need for new gridded and microwave power tubes is being met with new processes and materials.

Although low-power vacuum tubes have been largely replaced by solid-state ...
