Compact Ceramic Balun

Model TCW2-282+ is a miniature balanced/unbalanced (balun) RF transformer with a 1:2 impedance ratio and wide frequency range of 700 to 2800 MHz. Constructed with LTCC technology and supplied in a miniature 0603 package, the balun converts a secondary impedance of 25.0 ohms to a primary impedance of 50 ohms (1:2 ratio). Loss is minimal, with typical full-band insertion loss of 1.2 dB, while typical amplitude unbalance is within 1 dB and typical phase balance (relative to 180 deg) is within 13 deg.
