![]() ![]() Different impedances on the two wires on the input relative to a ground unbalances the circuit and subjects it to noise voltages relative to the ground reference. They are also used when an AC voltage on the input needs to be de-referenced from its input impedances, typically referred to as a ground level. ![]() Transformers are used in applications where the signal needs to be changed from one impedance to another. RF Transformers are transformers that are optimized for very high frequency signal applications. Transformers couple in proportion to the magnetic permeability of the core material through which the magnetic field is changing that links the two coils, and are usually extremely efficient when used within their design windows. ![]() The coupling is caused by the varying magnetic field inducing an electromotive force (EMF) in the other conductor, often referred to as a winding or coil. An RF transformer is an electromagnetic device that sits between two or more circuits and uses changes of electric signals and the principle of induction in a conductor to produce a varying magnetic field (flux) that couples energy through to another conductor. ![]()
