MABA-010321-CT1A42

Balun Overview

The MABA-010321-CT1A42 is a surface-mount RF balun manufactured by MACOM Technology Solutions. It operates within a frequency range of 50MHz to 1.2GHz and provides a 1:1 impedance transformation ratio between unbalanced and balanced ports. The component utilizes a transmission line transformer design housed in a compact 6-SMD (5 Leads) package with flat leads. Key electrical specifications include an insertion loss of 0.6dB, return loss of 1.65dB, and amplitude balance of 6.7 degrees at 8dB attenuation levels.

Balun Feature Summary

• Surface-mount transmission line transformer design for signal integrity
• 1:1 impedance conversion capability between unbalanced and balanced circuits
• Broadband operational range supporting high-frequency applications

Balun Applications

• CATV broadband systems
• FTTx network infrastructure
• RF signal distribution networks

Balun Procurement Notes

Verify the specific suffix CT1A42 against official MACOM documentation to confirm tape and reel packaging configuration and lead type. Ensure compatibility with automated pick-and-place equipment due to the flat lead SMD form factor. Cross-reference the active status with current distributor availability lists to confirm supply chain continuity.

Balun Selection Notes

Select this component when a 1:1 balun is required for frequencies up to 1.2GHz in space-constrained designs. The low insertion loss of 0.6dB makes it suitable for sensitive RF paths. Consider the 6-SMD footprint constraints during PCB layout planning to ensure adequate clearance for the flat leads.

Balun Part Context

This part belongs to MACOM's portfolio of audio and signal transformers, specifically designed for broadband applications. It serves as a critical interface component in modern telecommunications hardware, bridging single-ended and differential signal domains without significant signal degradation across its specified bandwidth.

Balun Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1:1 ratio, 50MHz-1.2GHz range, and 6-SMD package dimensions.
