NCS2-771-75+

Product Overview

NCS2-771-75+ is a 75 Ω, 1:2 LTCC balun developed for 240 MHz to 770 MHz broadband and video-frequency RF paths. It converts a single-ended 75 Ω line to a balanced interface while providing the impedance transformation commonly needed between coaxial distribution networks and differential tuner or amplifier circuitry.

Mini-Circuits performance data shows sub-1 dB typical insertion loss over the operating range, along with useful return-loss, amplitude-balance and phase-balance behavior. These measured ranges make the device well suited to gain-budget and symmetry analysis in terrestrial television, CATV and wideband receiver designs.
