LCAT1002-07

Overview

The LCAT1002-07 is a coaxial in-line RF fixed attenuator manufactured by L-com. It provides a nominal attenuation of 7 dB with an accuracy of ±0.5 dB across a frequency range from DC to 3 GHz. The component features SMA male-to-female connectors and operates at a maximum power rating of 2 W. It maintains a characteristic impedance of 50 Ohms and exhibits a Voltage Standing Wave Ratio (VSWR) of less than 1.2:1. The unit is designed for operation within a temperature range of -55°C to +125°C.

Feature Summary

• Coaxial in-line design with SMA male and female connectors
• Fixed 7 dB attenuation with high precision accuracy
• Robust construction suitable for wide temperature environments

Applications

• RF signal path attenuation in test and measurement equipment
• Signal level matching in wireless communication systems
• Protection of sensitive receiver inputs in radar applications

Procurement Notes

Verify the specific connector gender configuration and physical dimensions against the official L-com datasheet before integration. Confirm that the 2W power handling capability aligns with the peak and average power requirements of the target circuit. Ensure environmental specifications meet the operational temperature constraints of the deployment site.

Selection Notes

Select this model when a precise 7 dB reduction is required between DC and 3 GHz frequencies. The SMA interface makes it suitable for standard PCB or panel mount interconnects. Consider the 2W power rating to ensure thermal management is adequate for continuous wave operations within the specified temperature range.

Part Context

This component belongs to the LCAT series of passive connectorized attenuators. It serves as a discrete solution for controlling signal amplitude in RF circuits. The product is categorized under interconnect attenuators, distinct from variable or step attenuator families.

Replacement Considerations

Publicly documented parameter-equivalent substitutes include models from Cinch Connectivity Solutions, Pasternack, and Radiall USA, Inc. Verify electrical compatibility and mechanical fit before substitution.
