APPLICATIONSy Telecommunications
y 5G sub 6GHzPRODUCT OVERVIEW
Mini-Circuits’ BBFCG2-43+ is a tiny ceramic RF balun filter with an impedance ratio of 1:2, covering a variety of wirelesscommunications applications from 3600 to 4400 MHz. This model provides low insertion loss, low phase unbalance (relative to180°), low amplitude unbalance. 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.
