How to select a Fixed Attenuator
A fixed attenuator is a device that has a fixed attenuation value for a set frequency range. The key specifications to look for in an rf fixed attenuator are:
Frequency (MHz): This is the frequency over which the fixed attenuator can operate with while providing a constant level of attenuation with minimal reflections.
Attenuation (dB): This is the ratio of the output and input power levels. Fixed attenuators usally have a fixed attenuation value.
Power (W): The level of power that an attenuator can handle.
Package Type: RF fixed Attenuators are available usually available in the form of connectorized devices with various connector options – SMA, N Type, BNC etc.
