Microwave Engineering

A Travelling Wave Tube (TWT) is a specialized vacuum tube that amplifies microwave signals by interacting with an electron beam traveling through a helical slow-wave structure. It is widely used in radar, satellite communication, and electronic warfare due to its high power and broadband amplification capabilities.

A Reflex Klystron is a type of vacuum tube used to generate and amplify microwave signals. It operates on the principle of velocity modulation of an electron beam. Reflex Klystrons are widely used in radar systems, microwave communication, and signal generation due to their simplicity, compactness, and efficiency in producing high-frequency oscillations.
