Balanced to Unbalanced TC1.33-282+ RF Transformer 100 to 75 5 to 2800 MHz The Big Deal Very wide bandwidth, 5 to 2800 MHz CASE STYLE: AT224-1 Very good return loss over entire band Convenient 100/75 matching over a wide range of frequencies 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 100/75 implementations. Feature Advantages 5-2800 MHz bandwidth useful for CATV (forward & return), medical wireless and D2A/A2D, and Very wide bandwidth communications applications 0.3 dB amplitude and 6 phase unbalance aid rejection of even harmonics (in push-pull amplifiers) and Excellent amplitude and phase unbalance common mode signals (when used as a balun) Good return loss Efficient signal path across 100/75 transitions Flatness 0.1 dB across 50-1000 MHz CATV bands preserves gain flatness after impedance Low and flat insertion loss transformation Notes A.
