LCAT7467-7

Overview

The LCAT7467-7 is a fixed attenuator from L-com designed for RF applications. It provides a nominal attenuation of 7 dB with a tolerance of ±1 dB. The device operates within a frequency range of DC to 12 GHz. It features SMA connectors, specifically an SMA male plug and an SMA female jack interface. The unit is rated for a maximum power handling capacity of 2 Watts continuous wave (CW). Additionally, it maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1, ensuring efficient signal transmission across its specified bandwidth.

Feature Summary

• Provides precise 7 dB fixed attenuation for signal level control
• Operates effectively from DC up to 12 GHz frequency range
• Utilizes robust SMA coaxial connector interface design
• Supports high power handling up to 2 Watts continuous wave

Applications

• RF signal path attenuation in test and measurement equipment
• Impedance matching and signal conditioning in wireless communication systems
• Protecting sensitive receiver inputs from high-power signals

Procurement Notes

Verify the specific connector gender configuration upon ordering, as the LCAT7467-7 typically denotes an SMA male plug to SMA female jack arrangement. Confirm that the required attenuation value of 7 dB aligns with system design specifications. Ensure the operating environment remains within the 2 Watt maximum power rating to prevent damage. Check for any specific datasheet revisions or manufacturer updates prior to final procurement decisions.

Selection Notes

Select this component when a fixed 7 dB reduction is required within a 50-ohm system operating up to 12 GHz. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate if the 2 Watt power rating meets peak signal levels. Compare against other series models if different attenuation values or connector types are needed for the specific application requirements.

Part Context

This model belongs to L-com's LCAT7467 series of fixed attenuators. The series offers various attenuation values, including 2, 4, 5, 6, 7, 10, and 20 dB options. All variants share similar electrical characteristics, such as the DC to 12 GHz frequency range and 2 Watt power handling. The series utilizes standard SMA connectors for versatile integration into coaxial RF circuits.

Replacement Considerations

Direct substitutes include other LCAT7467 series parts with identical attenuation if minor variations exist, though exact matches are preferred. Cross-manufacturer equivalents must match the 7 dB attenuation, 50-ohm impedance, DC-12 GHz range, and SMA plug-to-jack configuration. Verify VSWR and power ratings to ensure performance parity.
