Detailed Description for TC4-19LN+
Product Overview
TC4-19LN+ targets broadband RF and IF interfaces from 10 MHz to 1900 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. 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 LN suffix denotes a low-profile mechanical version, so installed height and land pattern require separate attention. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing
Antrex Electronics can support sourcing of TC4-19LN+ 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.
