MABACT0059

Balun Overview

The MABACT0059 is a 1:1 transmission line transformer manufactured by MACOM Technology Solutions. It operates within a frequency range of 4.5 MHz to 3 GHz. The device features a primary impedance of 75 Ohms and is housed in a 6-SMD (5 Leads) flat lead surface-mount package. Electrical specifications include a maximum insertion loss of 8.4 dB and a minimum return loss of 15 dB. It supports an operating temperature range from -40°C to +85°C.

Balun Feature Summary

• Utilizes transmission line transformer architecture for balanced-to-unbalanced signal conversion
• Windings are welded directly to the package substrate to enhance mechanical reliability
• Lead-free construction eliminates lead content in the winding connections

Balun Applications

• CATV systems
• Satellite STB applications
• Subscriber terminal equipment

Balun Procurement Notes

Verify the specific ordering suffix when purchasing, as variants such as MABACT0059-TB exist with distinct packaging configurations. Confirm that the required quantity matches the manufacturer's standard pack size or available cut-tape options. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the DigiKey part number 1465-1311-2-ND for accurate stock availability and logistics details before finalizing orders.

Balun Selection Notes

Select this component when a 75-ohm impedance match is required for RF applications between 4.5 MHz and 3 GHz. The 1:1 ratio makes it suitable for direct impedance transformation without voltage scaling. Consider the surface-mount footprint for automated assembly lines. Verify thermal performance against the specified -40°C to +85°C operating range for your specific environmental conditions.

Balun Part Context

This component belongs to MACOM's portfolio of RF baluns and transformers designed for cable television and satellite communication infrastructure. It serves as a critical interface for signal integrity in subscriber-facing hardware. The design prioritizes reliability through substrate-welded windings, addressing common failure modes in traditional wire-wound transformers used in high-volume consumer electronics manufacturing.

Balun Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative MACOM baluns based on identical 1:1 ratio, 75-ohm impedance, and compatible SMD footprint dimensions if direct replacement is necessary.
