SurfaceMountWidebandRFTransformers
These wideband RF transformers were developed spe-
cificallyforusewithAnalogDevicesdigitaltoanaloghigh-
speed converters and provide excellent performance at
a very economical price. They come with a tapped
secondary and are packaged in a low profile, flat top
ceramic case that makes them ideal for pick and place
operations. They feature 400 V isolation and a 500 mA
maximumcurrentrating.Operatingtemperaturerangeis
–40°C to +85°C.
Applications include impedance matching, voltage or
currenttransformation,DCisolation,balanced/unbalanced
mixing, matching, power splitting, coupling and signal
inversion.
