NCS1-222-75+

Product Overview

NCS1-222-75+ is a 75 Ω Mini-Circuits LTCC balun intended for broadband RF paths from 950 MHz to 2.2 GHz. Its 1:1 ratio preserves the nominal port impedance while converting between single-ended and balanced circuitry, a common requirement when a 75 Ω coaxial path feeds a differential tuner, mixer or amplifier input.

The 3 W input-power rating and compact 0805 ceramic construction suit dense CATV, satellite IF and broadband receiver layouts. Published insertion-loss and phase-unbalance limits are useful when evaluating gain budget and differential symmetry; PCB pads, ground return and trace symmetry should follow the manufacturer layout to retain those characteristics.
