Though attenuator can mean a variety of things, when referred to in an RF or Microwave system it is a broadband resistive device that drops the amplitude of the signal going in by the designated amount, generally given in dB. Attenuators are most commonly designed for 50 ohm systems since the vast majority of RF and Microwave systems, outside of the cable TV and video industry, are 50 ohm systems. Attenuators are designed to maintain the impedance of the system into which they are connected. If terminated in a 50 ohm termination, an attenuator will provide a 50 ohm input impedance. If terminated in some other impedance different from 50 ohm the impedance will deviate from 50 ohms but will be closer to 50 ohms than the original termination. This is actually one of the common applications of attenuators, improving mismatches which improves VSWR.   READ MORE
