TC4-1TG2+

Balun Overview

The TC4-1TG2+ is a surface-mount RF transformer designed for unbalanced-to-balanced conversion. It operates within a frequency range of 0.5 to 300 MHz and features a 1:4 impedance ratio with a nominal 50-ohm system impedance. The device exhibits an insertion loss between 0.27 and 0.62 dB, while return loss ranges from 14.29 to 32.32 dB. It supports a maximum DC current of 30 mA and handles a power rating of 0.25 W. The component is housed in an AT224-3 package, measuring 3.8 x 3.8 mm, suitable for compact circuit designs.

Balun Feature Summary
