LAT-6+

Overview

The Mini-Circuits LAT-6+ is a surface-mount fixed RF attenuator providing 6 dB attenuation. It operates from DC to 2.5 GHz with a 50 Ohm impedance. The component features a TO-253-4 (TO-253AA) package and handles up to 500 mW power. Typical performance includes a maximum VSWR of 1.5 and insertion loss around 0.7 dB. Operating temperature ranges from -55°C to +85°C.

Feature Summary

• Provides precise 6 dB signal attenuation across a wide frequency range
• Designed for surface-mount integration in compact circuit layouts
• Maintains excellent return loss and flatness from DC to 2.5 GHz

Applications

• RF test and measurement equipment
• Signal conditioning in communication systems
• Impedance matching networks requiring fixed loss

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet, as ordering codes may include specific tolerance or packaging variations not detailed in general listings. Confirm RoHS compliance status directly with the supplier documentation. Ensure the procurement channel provides official Mini-Circuits traceability records to guarantee component authenticity and performance consistency for critical RF applications.

Selection Notes

Select this component when a fixed 6 dB loss is required within the 2.5 GHz bandwidth. The SMT form factor suits automated assembly processes. Evaluate thermal management needs given the 500 mW power rating. Compare VSWR specifications against system requirements to ensure signal integrity is maintained without excessive reflection losses in the transmission path.

Part Context

The LAT series represents Mini-Circuits' line of surface-mount fixed attenuators designed for high reliability. These components are engineered to provide stable attenuation values with minimal phase shift. The LAT-6+ specifically targets applications needing consistent signal reduction in dense PCB environments, offering a balance between electrical performance and physical footprint constraints typical in modern RF design.

Replacement Considerations

Direct substitutes include other Mini-Circuits models such as the LAT-10+ or LAT-3+ for different attenuation levels. Cross-brand equivalents require careful verification of package dimensions, pinout compatibility, and frequency response curves to ensure seamless integration without redesigning the surrounding circuitry.
