TTWB Series

Wideband RF Transformers

NOTE: We now offer an even more economical version of this series: PWB. It is electrically identical, requires slightly more board space and is lower in height. Existing customers will continue to be supported indefinitely.

Available in 1, 1.5, 2, 4 and 16 to 1 versions
Tapped or untapped configurations
Footprint comparable to Mini-Circuits TT Series
Low profile, flat top ceramic case for reliable pick and place mounting
400 V isolation; 1/4 Watt input RF power rating
Typical applications are as impedance or isolation transformer
Can also be used for balanced to unbalanced (balun) conversion
RoHS compliant. 260°C compatible. Tin-silver-copper over silver-platinum-glass frit terminations
COTS Plus tin-silver-copper and tin-lead terminations available
