LAT-7+

Overview

The LAT-7+ is a miniature fixed attenuator manufactured by Mini-Circuits, designed for surface-mount technology (SMT) applications. It provides a nominal attenuation of 7 dB across a wide frequency range from DC to 2500 MHz. The component operates with a characteristic impedance of 50 ohms and features a maximum Voltage Standing Wave Ratio (VSWR) of 1.5. It is housed in a SOT-143-4 package and supports a power handling capacity of 0.5 Watts. The device functions as a single-channel, 1-bit attenuator suitable for RF signal management.

Feature Summary

• Wideband operation spanning from DC to 2500 MHz
• Excellent VSWR performance ensuring signal integrity
• Miniature SMT package design for compact integration

Applications

• RF test and measurement systems
• Signal generation and measurement setups
• High-performance S-band upconverter designs

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm current specifications. Ensure compatibility with surface-mount assembly processes. Check for any updated environmental compliance certifications or packaging variations directly from Mini-Circuits official channels before finalizing procurement orders.

Selection Notes

Select this component when a fixed 7 dB attenuation is required within the DC to 2.5 GHz bandwidth. Consider the SOT-143-4 footprint for PCB layout constraints. Evaluate the 0.5 Watt power rating against system signal levels. Ensure the 50-ohm impedance matches the surrounding circuit topology to maintain optimal performance.

Part Context

This part belongs to the Mini-Circuits LAT series of fixed attenuators, which are widely used in RF and microwave engineering. The series offers various attenuation values and frequency ranges, providing standardized solutions for signal level adjustment. The LAT-7+ specifically addresses needs for moderate attenuation in high-frequency applications requiring small form factors.

Replacement Considerations

Consult Mini-Circuits official substitution guides for compatible alternatives. Verify that any substitute maintains identical electrical parameters, including 7 dB attenuation, DC-2.5 GHz range, and 50-ohm impedance. Ensure physical package compatibility if board space is constrained.
