LCAT1005-10

Overview

The LCAT1005-10 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a nominal attenuation of 10 dB with an accuracy of ±0.5 dB across a frequency range from DC to 18 GHz. The component supports a maximum input power of 2 W and maintains a Voltage Standing Wave Ratio (VSWR) of less than 1.30:1. It operates within a temperature range of -55°C to 125°C and features a 50 Ohm impedance. The unit utilizes SMA connectors, specifically a male plug to female jack configuration, housed in a stainless steel body.

Feature Summary

• Provides precise 10 dB signal attenuation with tight tolerance accuracy
• Operates effectively across a wide bandwidth from DC to 18 GHz
• Constructed with a durable stainless steel housing for environmental resilience
• Ensures low signal reflection through a VSWR rating below 1.30:1

Applications

• RF test and measurement equipment requiring stable signal reduction
• Wireless communication systems operating at microwave frequencies
• Signal conditioning in radar and electronic warfare applications

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as this model specifies a male-to-female interface. Confirm that the 2W power handling capacity is sufficient for the intended application's peak power levels. Ensure the operating environment falls within the specified -55°C to 125°C temperature range to maintain performance integrity and longevity of the component.

Selection Notes

Select this component when a fixed 10 dB attenuation is required up to 18 GHz. Consider the 2W power rating against expected signal levels to prevent damage. The SMA interface dictates compatibility with existing coaxial infrastructure. Stainless steel construction offers advantages in harsh environments compared to plated alternatives. Verify impedance matching to ensure minimal insertion loss in 50 Ohm systems.

Part Context

This part belongs to the LCAT1005 series of fixed attenuators from L-com. The series includes variants with different attenuation values, such as 3 dB, 6 dB, and 20 dB, sharing similar electrical characteristics and form factors. These components are standardized for use in general-purpose RF applications where consistent signal reduction is necessary without variable adjustment capabilities.

Replacement Considerations

Compatible substitutes include other L-com models like LCAT1005-03 or LCAT1005-20 if different attenuation values are acceptable. Third-party equivalents must match the 10 dB value, 18 GHz frequency limit, and SMA connector type. Verify that alternative parts meet the same 2W power and VSWR specifications to ensure functional parity.
