Device Overview
General Description
The MBAL-0220PSM is a GaAs passive MMIC balun in a 3mm QFN surface mount package. This high isolation balun features excellent amplitude and phase balance across its 2 to 20 GHz frequency range and offers a 2:1 impedance ratio. The 3mm QFN package is a lead free, RoHS compliant package compatible with standard leaded and lead-free solder reflows. The MBAL-0220PSM is an excellent choice for balanced amplifiers, clock distribution, and higher order Nyquist sampling in analog to digital converters. The MBAL-0220PSM is a higher isolation, smaller form factor version of the MBAL-0220SM.
