Device Overview
General Description
The MBALH-0R520CSP2 is a GaAs passive MMIC 1:1 balun that features excellent 32 dB common mode rejection over a 0.5 to 20 GHz operational bandwidth. The MBALH-0R520CSP2 is footprint compatible with the 2:1 MBAL-0R520CSP2, offering flexibility in system design. For ADC and DAC interface applications, the choice between the 1:2 and 1:1 configurations will depend on specific system requirements. This device is an ideal solution for digital beamforming and other higher-order Nyquist sampling applications, as well as clock distribution and balanced amplifier interfaces. Available in a lead-free, RoHS compliant 2.5 x 2.5 mm CSP2 package, it is compatible with standard pick-and-place assembly processes.

Mixed Mode Scattering Parameters in 50 Ohm Differential System
Mixed mode scattering parameters are used to characterize differential circuits. For baluns, this means that the 0° and 180° ports become a single 50Ω differential port and the common port remains the same 50Ω common port. For more information about 1:1 balun data, visitMBAL vs. MBALH Data. 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.
