How RF Transformers Work

how rf transformers workHow RF Transformers Work
Applications for RF transformers RF transformers are widely used in electronic circuits for : q Impedance matching to achieve maximum power transfer and to suppress undesired signal reflection. q Voltage, current step-up or step-down. q DC isolation between circuits while affording efficient AC transmission. q Interfacing between balanced and unbalanced circuits; example: balanced amplifiers.

Transformer circuits and impedance relationships When signal current goes through the primary winding, it generates a magnetic field which induces a voltage across the secondary winding. Connecting a load to the secondary causes an AC current to flow in the load. It is generally necessary to control terminating impedances of RF signal paths, especially in wide-band applicatio
