LAT-12+

Overview

The LAT-12+ is a fixed attenuator manufactured by Mini-Circuits, designed for surface-mount technology (SMT) applications. It provides a nominal attenuation of 12 dB with a maximum frequency range extending from DC to 2500 MHz. The component operates at a standard system impedance of 50 ohms and features a TO-253-4 package. Key electrical specifications include a maximum VSWR of 1.5 and a power handling capacity of 500 mW. It functions within an operating temperature range of -55°C to +85°C, ensuring reliability in various RF environments.

Feature Summary

• Provides precise 12 dB signal attenuation for RF circuit design
• Operates across a wide frequency spectrum from DC to 2500 MHz
• Utilizes SMT packaging for compact board integration
• Maintains stable performance under varying thermal conditions

Applications

• Wireless communication systems
• Test and measurement instrumentation
• Satellite communications
• CATV and broadband networks

Procurement Notes

Verify the specific datasheet version for the LAT-12+ to confirm exact mechanical dimensions and pinout configurations before finalizing PCB layout. Ensure that the selected supplier provides components with valid RoHS compliance documentation as indicated in official manufacturer records. Cross-reference the part number suffixes to guarantee compatibility with required environmental standards and material compositions.

Selection Notes

Select the LAT-12+ when a fixed 12 dB reduction is required in 50-ohm systems up to 2.5 GHz. Consider its SMT form factor for space-constrained designs requiring robust thermal performance. Evaluate the 500 mW power rating against peak signal levels to prevent damage. Compare VSWR specifications against system tolerance requirements to ensure minimal signal reflection in high-frequency applications.

Part Context

Mini-Circuits produces a broad portfolio of RF and microwave components, including attenuators like the LAT series. These devices are engineered for consistency and reliability in demanding electronic environments. The LAT-12+ belongs to this lineage, offering standardized attenuation values for use in commercial, industrial, and military-grade hardware where precise signal control is critical for system integrity.

Replacement Considerations

Direct substitutes may include other Mini-Circuits fixed attenuators with identical 12 dB attenuation and similar frequency ranges, such as variants in the same LAT family or comparable SMT packages. Verify that any replacement matches the 50-ohm impedance and physical footprint to maintain circuit compatibility without redesign.
