Coaxial load 

     Coaxial load, coaxial terminal, RF load, high-frequency load and microwave coaxial load are microwave passive single port devices, which are widely used in microwave equipment and microwave circuits. The main function of the load is to fully absorb microwave energy from the transmission line and improve the matching performance of the circuit. The load is usually connected to the terminal of the circuit, so it is also called terminal load or matching load.
