Detailed Description for TCM4-19+
Product Overview
TCM4-19+ is a Mini-Circuits wideband 1:4 core-and-wire RF balun transformer covering 10 MHz to 1.9 GHz. 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 7.01 dB minimum, phase balance of 6°.
Core-and-wire construction gives this family broad low-frequency response while retaining useful RF bandwidth for IF, HF, VHF and UHF circuitry. The 1:4 impedance ratio strongly affects voltage and current transformation, so the ratio and winding orientation must remain unchanged in an approved BOM. Additional published limits include RF power 0.25 W, DC current 30 mA.

Quality & Sourcing
Antrex Electronics can support sourcing of TCM4-19+ 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.
