General Description

The MBAL-0624PSM is a GaAs passive MMIC balun in a DFN surface mount package. This high isolation balun features excellent amplitude and phase balance across its 4 to 22 GHz frequency range and offers a 2:1 impedance ratio. The compact DFN package allows for extreme miniaturization of SMT footprints. The MBAL-0624PSM is an excellent choice for balanced amplifiers, clock distribution, and higher order Nyquist sampling in analog to digital converters.

Features

  • 2:1 Impedance Ratio
  • 6 to 24 GHz (Balanced to Unbalanced Transformer)
  • Insertion Loss as a Mode Converter, 1.7 dB Typical
  • Common Mode Rejection, 28 dB Typical
