Waveguide Variable Attenuators Continuously Rotary Stepped Manually

In microwave circuits, the power of signals is often very high. If excessive power cannot be fully controlled, it will easily cause many problems in the circuit, such as exceeding the maximum energy tolerance range of circuit components and causing various deviations. The use of waveguide variable attenuators can effectively meet the demand for reducing signal power and ensure the normal operation of microwave circuits.
The working principle of continuously variable attenuator is based on the propagation characteristics of electromagnetic waves in waveguides. It mainly consists of waveguides, impedance matching devices, and variable conductor blocks. When a signal passes through a waveguide, a portion of the energy is absorbed by the conductor block, thereby reducing the signal power
When the conductor block is a mechanical structure that can be manually adjusted by the user, it is a rotary stepped attenuators. The manually variable attenuators are indispensable helpers in electronic communication systems.
