TC133-282

Surface Mount 75 to 50Ω RF Transformer 5 to 2800 MHz 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 of frequencies TC1.33-282+ CASE STYLE: AT224-1 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 Very wide bandwidth Advantages 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) Excellent amplitude and phase unbalance 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 ISO 9001 ISO 14001 AS 9100 CERTIFIED P.O.
