Device Overview
General Description
The MBAL-0220CSP2 is a GaAs passive MMIC balun featuring a frequency range of 2 to 20 GHz. This balun offers low 1.9 dB insertion loss as a mode converter, excellent balance and 27 dB common mode rejection in a compact 2.5 mm CSP2 chip scale package. The leadfree, RoHS compliant CSP2 package is compatible with standard pick and place assembly. It is an ideal solution to interface into dataconverters for S-K band digital beamforming and other higher order Nyquist sampling applications, clock distribution, and balanced amplifiers.

Mixed Mode Scattering Parameters
Mixed mode scattering parameters are used to characterize differential circuits. For baluns, this means that the 0° and 180° ports become a single 100Ω differential port and the common port remains the same 50Ω common port. The two-port s-parameters of the balun are then characterized based on differential (d), common mode (c), or single-ended (s) signals. For example: Scs12 is the Common output response given a single ended input.
