SurfaceMountWidebandRFTransformers
These wideband RF transformers provide excellent performance at a very economical price. They are packaged in
a low profile, flat top ceramic case that makes them ideal
for pick and place operations. Operating temperature range
is –40° to +85°C.
Applications include impedance matching, voltage or current transformation, DC isolation, balanced/unbalanced
mixing, matching, power splitting, coupling and signal
inversion.
In addition to these parts, transformers with other combinations of impedance ratio, insertion loss, and frequency
response are available. They can be ordered with a untapped
secondary or with tapped primary and tapped secondary. For
custom parts or for free evaluation samples, contact Coilcraft
or visit www.coilcraft.com.
