TCM4-1WX+

Product Overview

Mini-Circuits TCM4-1WX+ provides 1:4 transformer operation across 3 MHz to 800 MHz. The 1:4 ratio establishes the intended relationship between the 50 Ω system ports while performing balanced/unbalanced conversion. Confirmed selection data includes insertion loss of 3.0 dB maximum, return loss of 9.01 dB minimum.

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 TCM4-1WX+ 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.
