Signal Transformer Market
A signal transformer is used in electronic devices as a step-up/step-down, impedance matching, or
isolating component. Increased advancement in technology pertaining to electronics drives growth of the
signal transformer market. Power transformers that carry high current are not suitable for use as signal
transformers. A transformer is an electrical device comprising two coils mounted on a core, namely
primary and secondary. The basic principle of working is that when the primary winding is connected to a
current supplying source and a signal passes into it, an electromagnetic force (EMF) is produced. This
electromagnetic force induces a voltage in the secondary coil, which is based on the number of windings
per coil and the number of turns. In a ‘step-up’ transformer, if the number of windings are more on the
secondary coil, the induced voltage is high as compared to the applied voltage. Likewise, in a step-down
transformer, the number of windings are more on the primary coil, and the induced voltage will be less
than the applied one.
Signal transformers find applications in electronic devices, especially those pertaining to
telecommunication, radio frequency, audio, video, and other general purposes. Signal transformers are
used when the signal from one circuit is transferred to another circuit and it needs to be coupled, or
stepped up or down or amplified, depending on the requirement. Signal transformers are also used for
phase shifting from stage to stage in an electronic device. Signal transformer products have provided
unparalleled innovative application-specific solutions to the electronics industry for more than 50 years.
On the basis of the type of signal used in signal transformers, they are classified into digital, audio,
electronic, RF, telecom/LAN. Digital transformers carry signals comprising discrete values, as opposed to
analog signals.
