RF Transformer

Surface Mount

TC1.33-282+

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.

Feature

Advantages

Very wide bandwidth

5-2800 MHz bandwidth useful for CATV (forward & return), medical wireless and D2A/A2D, and

communications applications

Excellent amplitude and phase unbalance

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)

Good return loss

Efficient signal path across 50/75Ω transitions

Low and flat insertion loss

Flatness ±0.1 dB across 50-1000 MHz CATV bands preserves gain flatness after impedance

transformation
