TCM3-1TX+

Product Overview

TCM3-1TX+ targets broadband balanced/unbalanced interfaces from 2 MHz to 500 MHz in a compact production package. The 1:3 ratio establishes the intended relationship between the 50 Ω system ports while performing balanced/unbalanced conversion. The confirmed frequency range, impedance relationship and package construction are the principal published selection points for this ordering code.

Core-and-wire construction gives this family broad low-frequency response while retaining useful RF bandwidth for IF, HF, VHF and UHF circuitry. The X suffix identifies a flat-lead or no-lead package version; its land pattern should be checked separately from the standard package in the same electrical family.

Quality & Sourcing

Antrex Electronics can support sourcing of TCM3-1TX+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance ratio, package style and winding configuration. Alternative approval should be based on the confirmed electrical limits and PCB footprint rather than on a similar family name.
