NCS2-222+

Product Overview

NCS2-222+ is a Mini-Circuits ceramic LTCC RF balun transformer for RF balanced/unbalanced conversion across 1.275 GHz to 2.2 GHz. The important published selection points for this part are its 1:2 impedance relationship, 5° typ phase specification, 0.4 dB typ amplitude-balance figure, and 1.0 dB; referenced to 0.6 dB mid-band loss insertion-loss rating. In a real RF layout this component is normally placed close to the transceiver, mixer, amplifier or RFIC port, because the transformer ratio, pad geometry and parasitic environment directly affect matching and differential balance. The GE0805C-1 / miniature LTCC package makes it suitable for compact RF modules and production SMT assembly. For sourcing and BOM replacement, NCS2-222+ should be treated as a frequency- and layout-sensitive RF component rather than a generic magnetic part.
