TC1.33-1T-75X+

Product Overview

TC1.33-1T-75X+ is a 1:1.33 balun designed to transform a 75 Ω single-ended signal into a 100 Ω balanced interface from 3 MHz to 500 MHz. The impedance relationship is useful in CATV return paths and broadband receiver circuitry that must connect coaxial infrastructure to differential electronics.

The datasheet highlights a typical 23 dB return loss and specifically identifies push-pull amplifiers, 75 Ω CATV return applications and balanced 50 Ω circuits as target uses. That application guidance distinguishes the part from generic unity-ratio baluns and makes the exact impedance transformation central to substitution decisions.
