LCAT1004-08

Overview

The LCAT1004-08 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in radio frequency circuits. It provides a precise attenuation value of 8 dB across a frequency range extending from DC to 6 GHz. The component features a power handling capacity of 2 watts and operates with a characteristic impedance of 50 Ohms. It utilizes N-type connectors, specifically configured as male-to-female, allowing for direct series integration into transmission lines. The housing is constructed from brass with a nickel finish, ensuring durability and consistent electrical performance in demanding environments.

Feature Summary

• Provides fixed 8 dB signal attenuation for RF applications
• Operates effectively from DC up to 6 GHz frequency range
• Supports 2W power handling capacity within 50 Ohm systems
• Features robust brass body with nickel plating for corrosion resistance

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment setups requiring precise signal reduction
• Integration into microwave circuit boards and modules

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as some sources indicate N Male to N Female construction. Confirm that the 6 GHz upper frequency limit aligns with the operational bandwidth needs. Ensure the 2W power rating exceeds the maximum expected signal power to prevent component damage. Check for compliance with relevant environmental standards if used in harsh conditions.

Selection Notes

Select this model when a fixed 8 dB reduction is required at frequencies up to 6 GHz. Consider the 50 Ohm impedance match for standard RF infrastructure. Evaluate the 2W power limit against peak signal levels. The N-type interface dictates compatibility with existing coaxial cabling and hardware. Brass-nickel construction offers reliability for general-purpose RF tasks.

Part Context

This component belongs to L-com's line of passive RF attenuators, which are essential for managing signal strength in high-frequency electronics. Fixed attenuators like the LCAT1004-08 provide stable, non-variable loss, unlike adjustable variants. They are critical for protecting sensitive downstream components from overload and ensuring accurate signal integrity in complex RF chains.

Replacement Considerations

Compatible substitutes include other 8 dB fixed attenuators with N-type connectors and similar power ratings, such as the LCAT1004-04 for lower attenuation or higher-power variants. Verify that replacement parts maintain the 50 Ohm impedance and 6 GHz frequency coverage to ensure seamless integration without signal reflection issues.
