LCAT7468-7

Overview

The LCAT7468-7 is a fixed RF attenuator manufactured by L-com, designed for in-line module applications. It provides a precise attenuation value of 7 dB within a frequency range extending from 0 Hz to 12 GHz. The component operates with a characteristic impedance of 50 Ohms and utilizes N-Type connectors, specifically featuring an N plug (male) interface on one end and an N jack (female) interface on the other. This configuration allows for direct series connection between coaxial cables or equipment ports without requiring additional adapters.

Feature Summary

• Provides fixed 7 dB signal attenuation across a wide DC to 12 GHz bandwidth
• Features N-Type male-to-female connector interface for direct in-line integration
• Maintains 50 Ohm characteristic impedance for standard RF system compatibility

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching and protection in microwave communication systems
• Signal conditioning in broadband antenna feed lines

Procurement Notes

Verify that the specific order matches the LCAT7468-7 designation to ensure the correct 7 dB attenuation value. Confirm that the N-Type male-to-female connector orientation aligns with the existing cabling infrastructure. Check datasheet specifications for power handling limits and VSWR requirements relevant to the intended operational environment before finalizing procurement.

Selection Notes

Select this component when a fixed 7 dB loss is required at frequencies up to 12 GHz. Choose the N-Type interface if connecting standard N-conductor systems. Consider the physical size and mounting style of the in-line module form factor against available space constraints in the assembly design compared to other attenuator types.

Part Context

This part belongs to the LCAT7468 series of fixed attenuators from L-com. The series offers various attenuation values ranging from 1 dB to 10 dB, all sharing similar electrical characteristics including the 50 Ohm impedance and 12 GHz frequency limit. The numbering suffix indicates the specific attenuation level, distinguishing it from adjacent models like LCAT7468-6 or LCAT7468-8.

Replacement Considerations

Direct substitutes include other LCAT7468 series units if different attenuation is acceptable, or equivalent 7 dB fixed attenuators from other manufacturers providing N-Type male-to-female interfaces and 12 GHz operation. Ensure replacement parts match the 50 Ohm impedance and physical connector dimensions for seamless integration.
