TT1-6+

Product Overview

TT1-6+ is a Mini-Circuits 1:1 core-and-wire RF balun transformer specified for 4 kHz to 300 MHz. Its unity ratio is used for broadband isolation and balanced conversion while preserving a 50 Ω nominal impedance.

The 4 kHz lower limit allows the same transformer to pass audio-adjacent, IF, HF, VHF and lower-UHF content. This standard version uses the flat-pack implementation; it is electrically related to KK81 and X65 variants but has a different board interface.

Quality & Sourcing

Antrex Electronics can support sourcing of TT1-6+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance relationship, package or connector configuration and any center-tap or suffix-specific mechanical details. Parts from the same transformer family may not be interchangeable when the ratio, port impedance, lead style or installed geometry changes.
