Wide Band RF Transformers
Coilcraft wide band transformers provide reliable per-
formance at a price considerably lower than currently
available equivalents.
The transformers are offered in tapped or untapped con-
figurations and are packaged in a low-profile DIP-style
plastic case. All parts are available in either a surface
mount version or a through-hole version that’s compat-
ible with standard DIP sockets. (For a smaller package
size and more values, see our TTWB Series.)
Applications include impedance matching, voltage or
current transformation, DC isolation, balanced/unbal-
anced mixing, matching, power splitting, coupling, and
signal inversion.
Custom wide band transformers with special combina-
tions of impedance ratio, insertion loss, frequency re-
sponse, and current handling are also available.
