Dummy Loads

Dummy loads, also known as terminators, are passive electronic devices that simulate an electrical load with minimal dissipating power. Various applications, such as testing and calibration of electronic equipment, especially in radio frequency (RF) and microwave systems, commonly use them.

Termination loads absorb RF energy to prevent reflections and ensure the proper functioning of transmitters, amplifiers, and other RF devices during testing and tuning processes. To minimize signal reflections and maintain signal integrity, these devices typically match the system’s impedance. Dummy loads, including resistive loads and reactive loads, play a crucial role in protecting equipment from damage due to mismatches or excessive reflected power.
