There are two main types of RF attenuators: fixed and variable. Fixed Attenuators: Provide a fixed amount of attenuation, typically designed using discrete or chip resistors. These can be further divided into:. Attenuators are designed to change the magnitude of the input signal seen at the input stage, while presenting a constant impedance on all ranges at the attenuator input. A compensated RC attenuator is required to attenuate all frequencies equally. Without this compensation, HF signal measurements. Let's look at the common types of attenuators Fixed attenuators, as their name suggests, are fixed or unchanging. These are used in applications that don't require changing levels of attenuation or where an occasional replacement of one attenuator with another is acceptable. Say we now add a 6 dB pad between.
