RF Transformers are two, or more, port passive devices with a wide range of uses for many RF applications. One of the most common uses of an RF transformer is the Balun, which provides efficient coupling between unbalanced transmission circuits and balanced circuits. Other common uses are for impedance matching between circuits of different impedances. ..

Basic Baluns The type of balun used in microwave RF designs depends on the bandwidth required, the operating frequency, and the physical architecture of the design. As differential power dividers, baluns can be transformers, capacitively and/or magnetically coupled transmission lines, hybrid couplers, or used in a combination of power divider and inverter. Baluns are used ..

Balun Performance Metrics There are many different types of baluns and the type of balun used in microwave RF designs depends on the bandwidth required, the operating frequency, and the physical architecture of the design. Most baluns usually contain two or more insulated copper wires twisted together and wound around or inside a core, magnetic ..
