496 results about "Impedance matching" patented technology

In electronics, impedance matching is the practice of designing the input impedance of an electrical load or the output impedance of its corresponding signal source to maximize the power transfer or minimize signal reflection from the load. In the case of a complex source impedance ZS and load impedance ZL, maximum power transfer is obtained when ZS=ZL* where the asterisk indicates the complex conjugate of the variable.
