A load is a microwave passive single port device, whose main function is to absorb all microwave energy from the transmission line, improve the matching performance of the circuit. The load is usually connected to the terminal of the circuit, so it is also called a terminal load or matching load. Provide matching impedance within a specified frequency range, which can be divided into resistive load, capacitive load, and inductive load. Used for terminating branch nodes or detection points in distributed system extension links.
