Detailed Description for NCS4-521+
Product Overview
NCS4-521+ is a Mini-Circuits ceramic LTCC RF balun transformer used for RF balanced/unbalanced conversion and impedance transformation. The confirmed published data for this exact ordering code is Frequency Range: 223 MHz to 520 MHz; Impedance Ratio: 1:4; Insertion Loss: 1.5 dB max; Phase Difference / Unbalance: 10°; Return Loss: 14.04 dB min; Package / Case: 0805 (2012 metric), 6 PC pad. These values make the part suitable for UHF front-end and instrumentation balun positions. In RF layouts the balun is normally placed close to the RFIC, mixer, amplifier or antenna matching network; the published ratio, passband and package should be preserved when replacing the part in an approved BOM.
