FAQ
A digital programmable attenuator is an RF or microwave component that electronically adjusts signal power to a selected attenuation level through digital control signals. It is widely used for signal level control, automated testing and dynamic RF systems.
Digital attenuators use electronic or digital control to change attenuation levels. A programmable attenuator allows users or external systems to select specific attenuation states. In RF applications, the two terms are often used together.
YUSNTECH digital programmable attenuators are available for RF and microwave frequency bands, with standard designs covering applications from low-frequency RF to 18 GHz. Custom frequency ranges are also available.
Typical attenuation ranges can reach 63 dB, with step resolutions such as 0.5 dB or 1 dB. Other attenuation ranges and step sizes can be customized according to system requirements.
TTL and parallel digital control are available for standard designs. Customized control interfaces and control logic can also be developed for specific system requirements.
Switching speed depends on the design and attenuation technology. Fast-switching models are available for dynamic RF control, automated test systems, radar and other high-speed applications.
Key parameters include frequency range, attenuation range, attenuation step, insertion loss, attenuation accuracy, VSWR, switching speed, input power, control interface and connector type.
Yes. Digital programmable attenuators are widely used in automated RF test systems for programmable signal level adjustment, calibration, dynamic range control and automated measurement.
Yes. Fast switching and programmable attenuation make them suitable for radar, electronic warfare, receiver testing and other RF systems requiring dynamic signal level control.
Yes. Custom solutions are available for frequency range, attenuation range, step size, control interface, switching speed, power handling, connector type, mechanical dimensions and environmental requirements.
