ADTT1-1+

Product Overview

ADTT1-1+ is a Mini-Circuits RF balun / transformer used to convert or couple RF signals between balanced and unbalanced circuit nodes. For this product page, the confirmed operating range is 300 kHz to 300 MHz, with an impedance specification of 50 / 50 Ohm. The part is supplied in a 6-SMD, Flat Leads package for surface mount assembly, making it suitable for compact RF boards where the transformer is part of the signal path rather than a general-purpose passive component. In sourcing and replacement work, the frequency range, impedance specification and package style are the key parameters to match before selecting an alternate transformer.
