MABA-008639-TC41T7

Balun Overview

The MABA-008639-TC41T7 is a surface-mount RF balun transformer manufactured by MACOM Technology Solutions. It operates within a frequency range of 6 MHz to 1000 MHz (1 GHz). The component provides an impedance transformation ratio of 1:4, converting between balanced and unbalanced signal paths. It is housed in a compact 6-SMD package with five leads and flat lead configuration. This device serves as the RoHS-compliant wire-welded version of the ETC4-1T-7 model, designed for efficient integration into high-frequency circuit boards.

Balun Feature Summary

• Provides 1:4 impedance transformation between balanced and unbalanced lines
• Operates across a wide frequency spectrum from 6 MHz to 1 GHz
• Utilizes a low-cost surface mount package for automated assembly

Balun Applications

• RF signal path balancing in communication systems
• Impedance matching in broadband amplifier circuits
• Integration into compact wireless transceiver modules

Balun Procurement Notes

Verify that the specific TC41T7 suffix corresponds to the required RoHS compliance and wire-welded construction variant when sourcing. Confirm the 6-SMD footprint matches the target PCB layout, noting the five-lead configuration. Ensure the supplier provides official MACOM documentation to validate the 1:4 ratio and frequency specifications against the design requirements.

Balun Selection Notes

Select this component when a 1:4 impedance step-up or step-down is required within the 6 MHz to 1 GHz band. It is suitable for designs prioritizing a surface-mount solution over through-hole alternatives. Consider the physical dimensions of the 6-SMD package during board space allocation. Verify that the insertion loss characteristics meet the system budget for the intended application frequency.

Balun Part Context

This part belongs to MACOM's E-Series of RF transmission line transformers. It functions as a direct replacement for the non-RoHS ETC4-1T-7 model, maintaining identical electrical performance while adhering to modern environmental standards. The series is characterized by its use of transmission line technology for broad bandwidth operation.

Balun Replacement Considerations

The MABA-008639-TC41T7 is the RoHS-compliant equivalent of the ETC4-1T-7. No other cross-model substitutes are documented in the provided data.
