TC1.33-1T-75+

Product Overview

TC1.33-1T-75+ is a 75 Ω, 1:1.33 transformer specified from 3 to 500 MHz. It performs balanced-to-unbalanced conversion while providing the impedance relationship used between a 75 Ω line and a higher-impedance balanced stage, rather than simply passing the same impedance through a unity-ratio winding.

Mini-Circuits identifies push-pull amplifiers, impedance matching and CATV applications among the intended uses. The AT224-1A package and configuration A suit compact broadband boards. Because the frequency range starts at 3 MHz, the part can serve return-path and IF duties as well as VHF/UHF signal sections, provided the connected differential load matches the 1.33 transformation.

Quality & Sourcing

Antrex Electronics can assist with sourcing TC1.33-1T-75+ for CATV, broadband and 75 Ω RF assemblies. A replacement should be checked for the same 75 Ω characterization, winding ratio, center-tap arrangement where present, package geometry and usable frequency range rather than selected only by transformer family name.
