TC4-14G2+

Product Overview

TC4-14G2+ targets broadband RF and IF interfaces from 200 MHz to 1400 MHz, using a 1:4 transformer relationship rather than a narrow tuned network. The 1:4 ratio lets a conventional 50 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 5.05 dB minimum.

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 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 TC4-14G2+ 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.
