Mini-Circuits’ BBFCG1-252+ is a tiny ceramic RF balun filter with an impedance ratio of 1:1, covering a variety of wireless communications applications from 2400 to 2500 MHz. This model provides low insertion loss, low phase unbalance (relative to 180°), low amplitude unbalance, and RF input power handling up to 1W. It provides DC iso- lation 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 (0.079″ x 0.049″ x 0.037″) suitable for harsh operating environments.
