Device Overview
General Description
The MBAL-0620SMG is a MMIC surface mount high isolation balun. This balun features excellent amplitude and phase balance across its 6 to 20 GHz frequency range and offers a 2:1 impedance ratio. It provides 18 typical isolation between the balanced ports, minimizing unwanted signal coupling. The balun also suppresses common-mode signals, helping maintain signal integrity in differential applications. The MBAL-0620SMG is form-fit compatible with the BAL-0620SMG and is intended for customers supporting existing designs. For new designs, we recommend the MBAL-0624PSM, which offers improved performance in a compact 1.3 x 2mm DFN package.
