TRS1-182-75+

Overview

The TRS1-182-75+ is a 1:1 core and wire transformer balun manufactured by Mini-Circuits. It operates over a wideband frequency range of 10 MHz to 1800 MHz. The device provides balanced transmission line functionality with characteristic impedances of 75 ohms on both ports. It features good return loss, typically 20 dB at the 1 dB band edge. The component is housed in a TT1618-1 surface mount case style and is suitable for tin/lead and RoHS solder systems.

Feature Summary

• Provides balanced transmission line conversion between unbalanced ports
• Operates as a wideband transformer across the 10 MHz to 1800 MHz spectrum
• Maintains high return loss performance within the specified bandwidth

Applications

• RF signal balancing in communication systems
• Impedance matching in 75-ohm RF circuits
• Broadband signal processing applications

Procurement Notes

Verify the specific datasheet version and mechanical drawing for the TT1618-1 package dimensions before integration. Confirm that the 75-ohm impedance specification aligns with the target circuit design requirements. Ensure compatibility with the intended soldering process, whether tin/lead or RoHS compliant, as indicated in the official documentation.

Selection Notes

Select this component when a wideband 1:1 balun is required for 75-ohm systems operating up to 1.8 GHz. Consider the surface mount form factor for automated assembly processes. Evaluate the typical 20 dB return loss against system VSWR requirements to ensure adequate signal integrity across the entire operational bandwidth.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components from DC to 86 GHz. The TRS1-182-75+ belongs to their portfolio of passive components designed for wireless communications, cable TV, and industrial control. This balun supports applications requiring reliable signal transformation in compact surface mount formats.

Replacement Considerations

Check for equivalent 1:1 75-ohm baluns from other manufacturers if supply constraints exist. Verify that any substitute matches the 10 MHz to 1800 MHz frequency range and maintains similar return loss characteristics. Ensure the replacement component fits the TT1618-1 footprint or allows for necessary layout adjustments.
