RF attenuators are essentially electrical resistor circuits that are put in line with an RF signal and reduce the signal strength. The amount of resistances used is what determines the amount of attenuation. Basic circuits used in attenuators are pi pads (π-type) and T pads. The lost power in the attenuator is converted into heat. →
