LCAT1005-02

Overview

The LCAT1005-02 is a coaxial in-line RF fixed attenuator manufactured by L-com. It provides a nominal attenuation of 2 dB with a maximum frequency range extending from DC to 18 GHz. The component features SMA male and female connectors, ensuring compatibility with standard 50 Ohm systems. It supports a power rating of 2 Watts and maintains a Voltage Standing Wave Ratio (VSWR) of 1.35:1. Constructed with stainless steel housing and a hex nut for secure installation, the unit weighs approximately 10 grams and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Coaxial in-line design with SMA male-to-female interface
• Stainless steel construction with hex nut body
• Fixed 2 dB attenuation across DC to 18 GHz range

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm microwave circuits
• Signal isolation between amplifier stages

Procurement Notes

Verify the specific datasheet version for the LCAT1005-02 to confirm current manufacturing status and compliance certifications. Ensure that the SMA connector gender configuration matches the system requirements, as variations may exist within product families. Cross-reference the operating temperature limits against environmental conditions to guarantee reliable performance during deployment.

Selection Notes

Select this model when a precise 2 dB attenuation value is required within an 18 GHz bandwidth. The SMA interface suits applications needing compact, high-frequency connectivity. Consider the 2W power handling capability relative to system signal levels. The stainless steel build offers durability for repeated connection cycles in laboratory or field environments.

Part Context

This component belongs to L-com's passive series of connectorized attenuators. It is part of a family offering various attenuation values and connector types, designed for interconnect applications. The LCAT1005 series specifically utilizes SMA connectors, distinguishing it from N-type or other interface variants available from the manufacturer.

Replacement Considerations

Direct substitutes include models with identical 2 dB attenuation, SMA M/F interfaces, and 18 GHz frequency ranges. Verify that alternative parts match the 50 Ohm impedance and 2W power rating. Check physical dimensions and mounting style compatibility if space constraints are critical.
