More about RF Variable Attenuators

Variable attenuators, like the name suggests are attenuators whose attenuation amplitude can be changed by varying the voltage or current to the device. These are used in application where it is required to continuously vary the signal level.

Key Specifications:

Type: These are usually Voltage Variable Attenuators or Current Variable Attenuators.

Frequency (MHz): This is the frequency range over which the attenuator can operate while maintaining its electrical characteristics.

Attenuation Range (dB): This is the ratio of the output and input power levels. The level of attenuation can be varied by voltage or current.

Power (W): The power that the attenuator can handle.

Impedance (Ohms): The impedance of an attenuator must match the circuit/system it is connected to; this will minimize any reflection within the circuit/system. Usually the impedance is 50 Ohms or 75 Ohms.
