Detailed Description for TCM1-43X+
Product Overview
TCM1-43X+ targets broadband RF and IF interfaces from 10 MHz to 4000 MHz, using a 1:1 transformer relationship rather than a narrow tuned network. 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 3 dB maximum, return loss of 14.24 dB minimum, phase balance of 7°.
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 X-family suffix identifies a top-hat or flat-lead construction that should be matched to the approved PCB footprint. Published absolute limits include RF power 0.4 W and DC current 30 mA. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing
Antrex Electronics can support sourcing of TCM1-43X+ 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.
