LCAT7467-4

Overview

The LCAT7467-4 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in high-frequency applications. It provides a nominal attenuation of 4 dB with a tolerance of ±1 dB across a frequency range from DC to 12 GHz. The device features SMA connectors, specifically a male plug to female jack configuration, ensuring compatibility with standard coaxial systems. It operates at a maximum continuous wave power of 2 Watts and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1. This component is constructed for reliable performance in broadband environments requiring precise signal attenuation.

Feature Summary

• Provides fixed 4 dB attenuation with ±1 dB tolerance
• Operates effectively from DC to 12 GHz frequency range
• Features SMA male plug to female jack connector interface
• Supports up to 2 Watts maximum continuous wave power

Applications

• RF signal path attenuation in test and measurement equipment
• Signal conditioning in broadband communication systems
• Impedance matching and power control in microwave circuits

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as SMA variants exist. Confirm that the 4 dB attenuation value aligns with the design specifications for the intended application. Ensure the operating environment remains within the specified 2 Watt power limit to prevent damage. Check for compliance certifications relevant to the deployment region before finalizing procurement decisions.

Selection Notes

Select this model when a precise 4 dB reduction is required within the DC to 12 GHz bandwidth. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate the 2 Watt power handling capability against peak signal levels. Compare against other attenuation values in the LCAT7467 series if different signal reduction levels are needed for the specific circuit design.

Part Context

This component belongs to the LCAT7467 series of fixed attenuators from L-com. The series includes various attenuation values such as 3 dB, 5 dB, 6 dB, and 8 dB, all sharing similar physical dimensions and connector types. These devices are engineered for consistent performance across a wide frequency spectrum, making them suitable for diverse RF applications requiring stable signal attenuation without active components.

Replacement Considerations

Direct substitutes include other LCAT7467 models with different attenuation values if the signal level requirement changes. Cross-brand replacements must match the 4 dB attenuation, DC-12 GHz range, and SMA connector type. Verify that alternative components meet or exceed the 2 Watt power rating and 1.35:1 VSWR specifications to ensure equivalent system performance.
