TCML1-11+

Product Overview

Mini-Circuits TCML1-11+ provides 1:1 transformer operation across 600 MHz to 1.1 GHz. The unity ratio preserves the nominal 50 Ω / 50 Ω port relationship while converting between single-ended and balanced circuitry. Confirmed selection data includes amplitude balance of 0.6 dB typical, phase balance of 8° typical.

Core-and-wire construction gives this family broad low-frequency response while retaining useful RF bandwidth for IF, HF, VHF and UHF circuitry. The package style, winding polarity and balanced pin orientation should be matched to the original PCB design. Additional published limits include RF power 0.25 W, DC current 30 mA.

Quality & Sourcing

Antrex Electronics can support sourcing of TCML1-11+ 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.
