Detailed Description for TC4-122-75X+
Product Overview
TC4-122-75X+ is a Mini-Circuits 75 Ω core-and-wire RF balun transformer specified for 40 MHz to 1250 MHz. The 1:4 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 2.5 dB maximum, return loss of 8.58 dB minimum, phase balance of 7°.
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 TC4-122-75X+ 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.
