Detailed Description for T4-1+
Product Overview
T4-1+ is a 1:4 Mini-Circuits RF transformer operating from 200 kHz to 350 MHz. The 1:4 ratio provides a substantial impedance transformation while also supporting balanced/unbalanced conversion, which is useful when a 50 Ω line must drive a higher-impedance differential stage.
Its bandwidth reaches from low-frequency IF through the lower-UHF region. The 0.25 W rating and 30 mA DC capability allow the transformer to be used in coupling and bias-compatible applications around mixers and push-pull amplifiers, subject to the winding and thermal limits in the datasheet.
