TRS1.5-182+

Overview

The TRS1.5-182+ is an RF balun transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 10MHz to 1.8GHz and features a 1.5:1 impedance transformation ratio between unbalanced and balanced ports. The component utilizes a 4-SMD module package configuration. Key electrical specifications include a maximum insertion loss of 2.8dB and a phase difference of 7.5 degrees. These parameters define its performance characteristics in high-frequency circuit applications.

Feature Summary

• Provides balanced-to-unbalanced signal conversion functionality
• Operates across a wide frequency spectrum from 10MHz to 1.8GHz
• Features a 1.5:1 impedance transformation ratio
• Constructed in a compact 4-SMD module package

Applications

• RF front-end circuits requiring impedance matching
• Balanced antenna interface connections
• High-frequency signal processing modules

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update internal component layouts or testing standards over time. Confirm that the 4-SMD footprint matches your PCB design constraints precisely. Ensure the supplier provides original manufacturer documentation to validate the 1.5:1 ratio and frequency range specifications against your system requirements.

Selection Notes

Select this component when a 1.5:1 impedance transformation is required rather than the standard 1:1 ratio. The 1.8GHz upper frequency limit suits many wireless communication bands. Consider the 4-SMD package size for space-constrained designs. Evaluate the 2.8dB insertion loss budget to ensure it meets system sensitivity requirements without excessive signal attenuation.

Part Context

This part belongs to the Mini-Circuits TRS series of RF transformers. The series includes various impedance ratios and frequency ranges. The TRS1.5-182+ specifically addresses niche applications needing non-standard 1.5:1 transformation. It complements other baluns in the portfolio that offer different ratios like 1:1 or 4:1 for broader system integration options.

Replacement Considerations

Direct substitutes must match the 1.5:1 ratio and 10MHz-1.8GHz range. Verify pin compatibility for the 4-SMD package before swapping. Alternative models from Mini-Circuits with similar specs should be cross-referenced using official parameter tables to ensure functional equivalence in the target circuit.
