TC9-1-75G2+

Product Overview

TC9-1-75G2+ is a Mini-Circuits 75 Ω high-ratio core-and-wire RF balun transformer specified for 0.3 MHz to 475 MHz. The 1:9 (8 Ω balanced / 75 Ω unbalanced) ratio lets a conventional 75 Ω system interface drive or receive a differential port with the intended impedance transformation. Confirmed selection limits include insertion loss of 3 dB maximum, return loss of 7.44 dB minimum.

The usable range crosses IF, HF, VHF and much of the UHF spectrum, which suits broadband equipment that cannot be served by a narrow tuned balun. The G2 suffix identifies the AT224-3 package option used for automated surface-mount assembly. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing

Antrex Electronics can support sourcing of TC9-1-75G2+ for production, repair and shortage requirements. Incoming verification should compare the exact ordering code, frequency band, impedance relationship, package style and any center-tap or suffix-specific configuration. A part from the same transformer family should not be substituted solely because its headline bandwidth overlaps.
