Attenuators are usually passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. For higher frequencies precisely matched low voltage standing wave ratio (VSWR) resistance networks are used. Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching
