TC4-25X+

Product Overview

Mini-Circuits TC4-25X+ provides balanced/unbalanced RF conversion across 500 MHz to 2500 MHz in a compact surface-mount implementation. The 1:4 ratio lets a conventional 50 Ω system interface drive or receive a differential port with the intended impedance transformation. The exact frequency range and impedance relationship are the primary confirmed selection parameters for this version.

Its passband covers UHF and lower microwave allocations used by cellular, telemetry, broadband radio and RF instrumentation while retaining transformer-based single-ended-to-differential conversion. The X-family suffix identifies a top-hat or flat-lead construction that should be matched to the approved PCB footprint. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing

Antrex Electronics can support sourcing of TC4-25X+ 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.
