MABA-011028

Balun Overview

The MABA-011028 is a single-channel surface-mount balun manufactured by MACOM Technology Solutions. It operates within a frequency range of 600 MHz to 1700 MHz and provides a 50/50 Ohm impedance transformation ratio with a 1:1 turns ratio. The device features an insertion loss of 1.3 dB maximum and a return loss of -30 dB minimum, with a phase difference of 1°. It is housed in a compact module package measuring 4.21 mm x 4.21 mm x 2.63 mm and supports operating temperatures from -40°C to +115°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF applications
• Utilizes transmission line transformer technology for wideband performance
• Designed for high-reliability surface-mount integration

Balun Applications

• RF front-end modules requiring impedance matching
• Wireless communication systems operating in the UHF/L-band spectrum
• Test and measurement equipment signal conditioning

Balun Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm lot traceability and RoHS compliance documentation prior to procurement. Ensure storage conditions maintain integrity given the component's age. Validate mechanical dimensions against current PCB layout requirements to ensure compatibility with existing assembly processes.

Balun Selection Notes

Select this component when a 50-ohm balanced output is required from a 50-ohm unbalanced source within the 600-1700 MHz band. Consider the specified insertion loss and return loss metrics for signal integrity requirements. Evaluate the thermal operating range against environmental constraints. Assess the physical footprint against available board space limitations.

Balun Part Context

This balun belongs to MACOM's portfolio of RF passive components designed for telecommunications and industrial applications. It serves as a critical interface element for converting differential signals to single-ended formats or vice versa. The component supports designs requiring stable impedance transformation across broad frequency ranges without active power consumption.

Balun Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified documentation. Due to the discontinued status, direct replacements may require design re-evaluation. Consult MACOM technical support for potential obsolescence management strategies or alternative solutions compatible with the original specifications.
