TT1-6-KK81+

Product Overview

TT1-6-KK81+ is a Mini-Circuits KK81-packaged 1:1 core-and-wire RF balun transformer specified for 4 kHz to 300 MHz. The KK81 version provides the same wideband unity-ratio transformer function in a gull-wing surface-mount package.

It supports low-frequency signal coupling through VHF and lower-UHF applications, including balanced antennas and push-pull stages. The KK81 gull-wing outline is the defining difference from the flat-pack TT1-6+ and through-hole TT1-6-X65+ versions.

Quality & Sourcing

Antrex Electronics can support sourcing of TT1-6-KK81+ 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.
