TC9-1X+

Product Overview

TC9-1X+ targets broadband RF and IF interfaces from 2 MHz to 200 MHz, using a 1:9 transformer relationship rather than a narrow tuned network. The 1:9 ratio lets a conventional 50 Ω system interface drive or receive a differential port with the intended impedance transformation. Confirmed selection limits include insertion loss of 3 dB maximum, return loss of 6.08 dB minimum, phase balance of 1°.

The specified range is aimed at low-frequency IF, HF and VHF signal chains where transformer isolation and controlled impedance conversion are required over a broad bandwidth. The X-family suffix identifies a top-hat or flat-lead construction that should be matched to the approved PCB footprint. The installed result also requires the published land pattern and electrically symmetrical balanced connections.

Quality & Sourcing

Antrex Electronics can support sourcing of TC9-1X+ 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.
