Surface Mount Wideband RF Transformers

These wideband RF transformers provide excellent perfor-

mance at a very economical price. They come tapped or

untapped 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 maximum current

rating. Operating temperature range is -40° to +85° C.

Applications include impedance matching, voltage or cur-

rent transformation, DC isolation, balanced/unbalanced

mixing, matching, power splitting, coupling and signal

inversion.
