Product Overview
The TC1.33-282+ is a mini wideband tri-filar transformer, measuring approximately 4 mm on all sides. The plastic substrate,
5-pad design is aqueous washable and RoHS compliant, featuring a square core and all welded wire construction for
repeatability and reliability in balanced-to-unbalanced 50/75Ω implementations.
The Big Deal
• Very wide bandwidth, 5 to 2800 MHz
• Very good return loss over entire band
• Convenient 50/75Ω matching over a wide range
75 to 50Ω
Very wide bandwidth
Excellent amplitude and phase unbalance
Good return loss
Low and flat insertion loss

5 to 2800 MHz
5-2800 MHz bandwidth useful for CATV (forward & return), medical wireless and D2A/A2D, and
communications applications
0.3 dB amplitude and 6° phase unbalance aid rejection of even harmonics (in push-pull amplifiers) and
common mode signals (when used as a balun)
Efficient signal path across 50/75Ω transitions
Flatness ±0.1 dB across 50-1000 MHz CATV bands preserves gain flatness after impedance
