Cryogenic RF Components | Advantages, Applications, Manufacturers

This page covers Cryogenic RF Components including their advantages, applications and manufacturers. The benefits or advantages of Cryogenic components used in RF and Microwave industry are also mentioned.

What are Cryogenic RF Components ?

The components which operate at ultra low temperatures in cryogenic environments and operates in radio frequency range of electromagnetic spectrum are called cryogenic RF components.

The common cryogenic RF components and devices used in microwave system designs include Cryogenic attenuator, Cryogenic amplifier, Cryogenic coupler, Cryogenic diplexer, Cryogenic bias-tee, Cryogenic filter, Cryogenic RF choke, Cryogenic switches, Cryogenic isolators, Cryogenic circulators, Cryogenic termination, Cryogenic connectors and cables etc.

Applications of Cryogenic RF Components

Following are the typical applications of Cryogenic RF components.
➨Quantum Computing
➨Missiles and satellites for space applications
➨MRI (Magnetic Resonance Imaging)
➨Radio astronomy
➨STM research
➨Particle physics research
➨Electron spin resonance measurement systems

Benefits or advantages of Cryogenic RF Components

Following are the benefits or advantages of Cryogenic RF Components:
➨The components can be used for very low temperature applications usually in the range from -150oC (~ 120 K) to -273oC (0 K).
➨Stable performance over large temperature variation
➨They generate ultra low noise.
➨Components offer high power density. Hence they output large amounts of energy based on their volume.
➨The components support very low power dissipation to meet cryogenic temperatures.
