LCAT7437-4

Overview

The LCAT7437-4 is a fixed RF attenuator from the LCAT7437 series, manufactured by L-com. It provides an attenuation value of 4 dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range of DC to 4 GHz and supports an input power rating of 2 Watts. It utilizes BNC connectors for interface.

Feature Summary

• Fixed 4 dB attenuation
• 50 Ohm impedance
• DC to 4 GHz frequency range
• BNC male to female coaxial package

Applications

• RF signal level reduction
• Impedance matching in test setups
• Signal conditioning for wireless systems

Procurement Notes

Verify the specific model suffix corresponds to the required attenuation value. Confirm connector gender compatibility (male to female) for system integration. Ensure operating frequency and power ratings align with application requirements before procurement.

Selection Notes

Select this component when a precise 4 dB loss is required at 50 Ohms. Consider the BNC interface constraints and 2W power handling capability. Evaluate frequency response needs up to 4 GHz against alternative attenuator values if different loss characteristics are needed.

Part Context

Part of the LCAT7437 series offering various fixed attenuation values. Designed for versatile coaxial applications using standard BNC connectors. Manufactured by L-com for RF and microwave environments.

Replacement Considerations

Check for other LCAT7437 variants with different dB ratings. Verify equivalent 50 Ohm fixed attenuators from other manufacturers with matching BNC interfaces and frequency/power specs.
