TC1-1-13M-34+

Balun Overview

The TC1-1-13M-34+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 47 MHz to 1.4 GHz, providing impedance transformation between unbalanced and balanced circuits with 50 Ohm ports on both sides. The component features a maximum insertion loss of 1.5 dB and a minimum return loss of 14.32 dB, ensuring efficient signal transmission. It maintains a phase difference of 3° for accurate signal balancing. Designed for reliability, it supports a maximum DC current of 30 mA and handles a power rating of 250 mW. The device functions within an operating temperature range of -40°C to +85°C and is housed in a compact 5-SMD module package.

Balun Feature Summary

• Provides balanced-to-unbalanced conversion for RF signals across the 47 MHz to 1.4 GHz spectrum
• Ensures signal integrity with low insertion loss and high return loss specifications
• Maintains precise phase balance with a 3-degree phase difference tolerance
• Supports direct surface mount integration into PCB layouts

Balun Applications

• RF front-end circuitry requiring impedance matching between 50 Ohm systems
• Signal distribution networks in communication equipment
• Balanced mixer or amplifier input/output stages
• Wireless infrastructure components operating in VHF/UHF bands

Balun Procurement Notes

Verify that the specific suffix '-34+' matches the required 47 MHz to 1.4 GHz operational bandwidth, as other variants in the series may differ significantly. Confirm that the 5-SMD package dimensions align with the target PCB footprint. Ensure that the 1.5 dB insertion loss limit meets system sensitivity requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate thermal management capabilities given the 250 mW power rating and operating temperature constraints.

Balun Selection Notes

Select this component when a dedicated balun function is required for frequencies up to 1.4 GHz. The 50/50 Ohm impedance configuration makes it suitable for standard RF systems. Consider the compact SMD form factor for space-constrained designs. Evaluate the 3-degree phase accuracy against system phase noise requirements. Compare performance metrics against alternative baluns if wider bandwidth or lower loss is necessary for the specific application.

Balun Part Context

This part belongs to the Mini-Circuits TC1 series of audio and signal transformers. These components are designed for surface mount technology, offering robust performance in RF applications. The series includes various models tailored for different frequency ranges and impedance configurations, allowing engineers to select appropriate solutions for diverse signal processing needs.

Balun Replacement Considerations

Direct substitutes include other Mini-Circuits baluns with similar 50/50 Ohm specifications and comparable frequency coverage. Verify that any replacement maintains the 47 MHz to 1.4 GHz range and 5-SMD package compatibility. Cross-reference phase difference and insertion loss limits to ensure equivalent signal performance.
