Voltage-Controlled Waveguide Tunable Attenuator
A waveguide voltage‑controlled variable attenuator is an active control device that continuously, rapidly, and steplessly adjusts the attenuation of RF signals in response to an external DC control voltage (or current). By varying the bias voltage applied to the control port, it dynamically alters the equivalent impedance of the solid‑state component, thereby modulating the proportion of electromagnetic waves absorbed or reflected within the waveguide. It serves as a critical building block for high‑speed closed‑loop control, fast pulse modulation, and modern adaptive RF systems.
• Operating frequency range: 40 GHz to 220 GHz
• Attenuation range: 25 dB to 40 dB, continuously adjustable via voltage control.
• Maximum input power: 20 dBm
