LCAT7493-3

Overview

The LCAT7493-3 is a fixed RF attenuator manufactured by L-com, designed for in-line module applications. It provides a nominal attenuation of 3 dB across a frequency range from 0 Hz to 6 GHz. The component features a power rating of 10 Watts and operates with a characteristic impedance of 50 Ohms. The physical interface consists of a 2.2-5 male connector on one end and a 2.2-5 female connector on the other, facilitating direct connection within RF signal chains.

Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Operates effectively from DC up to 6 GHz frequency range
• Supports high power handling capability rated at 10 Watts
• Features robust brass construction for durability

Applications

• RF signal chain power reduction
• Impedance matching in microwave systems
• Test and measurement equipment calibration
• Telecommunications infrastructure components

Procurement Notes

Verify the specific connector gender configuration (male-to-female) against system requirements before procurement. Confirm that the 10W power rating aligns with peak operational loads. Ensure the 2.2-5 interface type matches existing cabling standards. Request official datasheets to validate frequency response characteristics for critical 6 GHz applications.

Selection Notes

Select this model when a fixed 3 dB attenuation value is required for signals up to 6 GHz. Consider the 10W power rating for high-power transmission lines. The mixed 2.2-5 connector interface requires compatible adapters or cables. Evaluate thermal management needs given the brass housing and power dissipation capabilities.

Part Context

This component belongs to L-com's line of fixed RF attenuators, specifically engineered for broadband performance. The LCAT series typically utilizes brass bodies for mechanical stability and thermal conductivity. This particular model bridges different connector interfaces while maintaining consistent 50 Ohm impedance throughout the signal path.

Replacement Considerations

Direct substitutes must match the 3 dB attenuation, 6 GHz bandwidth, and 10W power rating. Verify compatibility of 2.2-5 male/female interfaces. Alternative models from other manufacturers require identical electrical specifications and physical dimensions for seamless integration.
