ADT2-1T+

Product Overview

ADT2-1T+ is a Mini-Circuits RF balun / transformer with a confirmed 1:2 impedance specification and an operating range of 400 kHz to 450 MHz. It is used where the RF path needs both transformer coupling and an impedance step between the source and load networks. Compared with a generic magnetic transformer, this part is selected by RF designers because the published insertion-loss, return-loss and phase-balance values are tied to a defined Mini-Circuits package and mounting style. The 6-SMD, flat leads surface-mount format supports automated assembly and allows the transformer to sit near mixers, amplifiers, differential ADC/RFIC inputs or IF stages. When replacing this item, the ratio, frequency span and package must remain aligned with the approved RF layout because the transformer is part of the matching network.
