TCM1-63AX-2+

Product Overview

Designed for 10 MHz to 6000 MHz, TCM1-63AX-2+ combines wideband transformer coupling with a defined 1:1 impedance relationship. The unity ratio preserves the nominal 50 Ω / 50 Ω relationship while providing isolation and conversion between single-ended and differential nodes. Confirmed selection limits include insertion loss of 2.5 dB maximum, return loss of 9.42 dB minimum, phase balance of 8°, amplitude balance of 0.5 dB.

The span reaches from low-frequency IF or HF into multi-gigahertz wireless bands, allowing one transformer to serve broadband receivers, test equipment and multi-band RFIC interfaces. The additional ordering suffix marks a distinct qualified version; the exact winding and mechanical configuration should remain unchanged in an existing BOM. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing

Antrex Electronics can support sourcing of TCM1-63AX-2+ 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.
