TCW4-582+

Overview

The TCW4-582+ is an RF balun manufactured by Mini-Circuits, designed for operation within the 5 GHz to 5.8 GHz frequency range. It features a 1:4 impedance transformation ratio and utilizes LTCC technology housed in a compact 0603 (1608 Metric) surface-mount package with six pad connections. Key electrical specifications include a maximum insertion loss of 1.7 dB, a minimum return loss of 9.5 dB, and a phase difference of 13°. The component supports a maximum operating temperature of +125°C and complies with RoHS3 standards.

Feature Summary

• Provides balanced-to-unbalanced signal conversion using Low Temperature Co-fired Ceramic (LTCC) construction for reliable high-frequency performance.
• Delivers a 1:4 impedance transformation ratio suitable for interfacing between 50-ohm unbalanced lines and balanced circuits.
• Engineered for surface-mount assembly in a small 0603 footprint to facilitate dense PCB layouts.

Applications

• RF signal routing in wireless communication systems
• Impedance matching networks for balanced antenna interfaces
• Signal processing stages in microwave transceivers

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format, such as tape and reel or cut tape, matches your production requirements. Confirm that the component meets all necessary regulatory compliance standards for your target market. Cross-reference the manufacturer part number with official datasheets to validate technical parameters before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is required for 5 GHz to 5.8 GHz applications needing a 1:4 impedance transformation. Consider the 0603 package size for space-constrained designs and evaluate the insertion loss and phase difference specifications against system sensitivity requirements. Ensure the surface-mount form factor aligns with your manufacturing capabilities.

Part Context

This component belongs to the TCW4 series of RF baluns from Mini-Circuits, which are widely used in microwave and radio frequency applications. The series leverages LTCC technology to provide stable performance across various frequency bands. The TCW4-582+ specifically targets the 5 GHz to 5.8 GHz range, offering a standardized solution for balanced-to-unbalanced conversion in modern electronic devices.

Replacement Considerations

Consult official Mini-Circuits documentation for verified substitute part numbers within the TCW4 series or other compatible balun families. Ensure any replacement maintains the same frequency range, impedance ratio, and package dimensions to preserve circuit integrity without redesigning the PCB layout.
