Part Number Options Model Number Description MBAL-0104SM1 1 GHz to 4 GHz MMIC Balun, Surface Mount EVAL-MBAL-0104 Connectorized Evaluation Module 1Note: For port locations and I/O designations, refer to the drawings on page 2 of this document. The MBAL-0104SM is a GaAs passive MMIC balun in a 4mm QFN surface mount package. It features excellent amplitude and phase balance across its 1 to 4 GHz frequency range that offers a 1:2 impedance ratio. The 4mm QFN package is a lead free, RoHS compliant package compatible with standard leaded and lead-free solder reflows. SMA connectorized evaluation packages are available. The MBAL- 0104SM is an excellent choice for balanced amplifiers, clock distribution, and higher order Nyquist sampling in analog to digital converters.

Passive MMIC 1-4GHz Surface Mount Balun MBAL-0104SM Page 3 Copyright © [2017-2020] Marki Microwave, Inc. | Rev. D Three port scattering parameters measured as three single-ended 50Ω ports showing relationship between any two ports. For example: S21 and S31, often referred to as insertion loss of a balun, is the output response on ports 2 and 3 with an input stimulus on port 1.

Passive MMIC 1-4GHz Surface Mount Balun MBAL-0104SM Page 4 Copyright © [2017-2020] Marki Microwave, Inc. | Rev. D 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.

Revision History

Revision code Revision Date Comment D October 2020 Specs table update DATA SHEET NOTES: 1. Balun measured as a splitter. Combiner measurement is equivalent to splitter measurement. 2. Specifications are subject to change without notice. Contact Marki Microwave for the most recent specifications and data sheets. 3. Catalog circuits are continually improved. Configuration control requires custom model numbers and specifications Note: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in per manent damage to the device.
