LCAT7468-3

Overview

The LCAT7468-3 is a fixed attenuator from L-com designed for RF applications. It provides an attenuation value of 3 dB with a tolerance of ±1 dB. The component operates within a frequency range of DC to 12 GHz and maintains a characteristic impedance of 50 ohms. It features N-type connectors, specifically a male plug to female jack configuration. The maximum continuous wave power rating is 2 Watts. The device exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• N-type connectorized interface for reliable interconnection
• Broadband operation supporting frequencies up to 12 GHz

Applications

• RF signal path attenuation in test and measurement equipment
• Impedance matching in microwave communication systems
• Signal level adjustment in antenna feed lines

Procurement Notes

Verify the specific part number suffix against official L-com documentation to confirm connector gender and attenuation value. Ensure the operating frequency does not exceed the 12 GHz limit and that power requirements remain within the 2 Watt CW rating. Confirm impedance compatibility with system components before integration.

Selection Notes

Select this component when a precise 3 dB reduction is required in a 50 ohm system. Consider the N-type connector size constraints and the 12 GHz upper frequency limit. Evaluate thermal management needs relative to the 2 Watt power handling capability. Compare VSWR specifications against system return loss requirements.

Part Context

This model belongs to the LCAT7468 series of fixed attenuators manufactured by L-com. The series offers various attenuation values while maintaining consistent N-type connector interfaces and broadband performance characteristics. These components are engineered for stability in RF environments requiring predictable signal attenuation.

Replacement Considerations

Compatible substitutes include other LCAT7468 series variants with different attenuation values, such as LCAT7468-8 or LCAT7468-9, provided the specific dB requirement differs. Cross-manufacturer replacements must match the 50 ohm impedance, N-type connector geometry, and 12 GHz frequency range.
