Product Overview
This RF Transformer, model JXDBT3F-434PT-S226-2S, is designed for Frequency Mixer applications, CATV, TVB-D, HomePlug AV MAC and PHY, and MII/RMII host interfaces. It incorporates common mode chokes to prevent signal interference and improve the signal-to-noise ratio. The transformer also provides isolation, enhancing transmitter and receiver circuitry balance while reducing common mode noise and EMI. Materials used are UL94V-0 recognized and meet IEC 695-2-2 standards. Designed for compact devices, it converts between unbalanced and balanced signals in tuner circuits for terrestrial digital broadcast. Windings utilize paired or triple wires for uniformity, and base pins allow direct PCB mounting. It is ideal for double-balanced mixers, broadband transformers, transistors, and impedance conversion, with options for different inductance values and Q specifications.
