Mini-Circuits’ TCW2-362+ is a tiny ceramic RF balun transformer with an impedance ratio of 1:2, covering a variety of wireless communications applications from 2150 to 3600 MHz. This model provides low insertion loss, low phase unbalance (relative to 180°), low amplitude unbalance. It provides DC isolation from input to output allowing it to be used for DC biasing of external circuits at the output. Fabricated using LTCC technology, the unit comes housed in a tiny, rugged ceramic package (0.06 x 0.03 x 0.02”) suitable for harsh operating environments.
