NCS1-112+

Product Overview

NCS1-112+ is a Mini-Circuits LTCC RF balun transformer for RF balanced/unbalanced conversion across 700 MHz to 1.1 GHz. The important published selection points for this part are its 50 Ω / 50 Ω impedance relationship, 13° phase specification, and 1.2 dB max 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 0805 (2012 metric), 6 PC pad package makes it suitable for compact RF modules and production SMT assembly. For sourcing and BOM replacement, NCS1-112+ should be treated as a frequency- and layout-sensitive RF component rather than a generic magnetic part.
