LCAT1006-05

Overview

The LCAT1006-05 is a fixed RF attenuator manufactured by L-com, designed for in-line module applications. It provides a nominal attenuation of 5 dB with an accuracy of ±1 dB. The component operates across a frequency range from DC to 18 GHz and supports a maximum input power of 2 Watts. It features SMA connectors (male to female) and maintains a system impedance of 50 Ohms. The unit exhibits a Voltage Standing Wave Ratio (VSWR) of less than 1.35:1 and functions within an operating temperature range of -55°C to 125°C.

Feature Summary

• Provides fixed signal attenuation of 5 dB for RF circuit management
• Operates effectively from DC up to 18 GHz frequency range
• Supports high power handling capability of 2 Watts maximum input
• Utilizes SMA male-to-female connector interface for direct integration

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Signal path protection in wireless networks

Procurement Notes

Verify the specific datasheet version provided by L-com or authorized distributors to confirm current manufacturing status and technical specifications. Ensure that the SMA connector gender configuration matches the system requirements. Cross-reference the part number against official L-com catalogs to validate authenticity and availability through legitimate supply channels before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5 dB attenuation is required within a 50 Ohm system architecture. The device is suitable for applications demanding operation up to 18 GHz with 2W power handling. Consider the SMA interface compatibility and the specified VSWR performance metrics relative to system loss budgets. Evaluate thermal management needs given the -55°C to 125°C operating range for environmental suitability.

Part Context

This model belongs to the LCAT1006 series of fixed attenuators from L-com. The series includes variants with different attenuation values, such as the LCAT1006-01 (1 dB) and LCAT1006-06 (6 dB). All models in this line share similar physical characteristics, including the 2W power rating, DC-18 GHz frequency range, and SMA connector types, differing primarily in their specific attenuation levels.

Replacement Considerations

Direct substitutes include other LCAT1006 series parts like LCAT1006-01 or LCAT1006-06 if different attenuation values are acceptable. Third-party equivalents must match the 5 dB attenuation, 50 Ohm impedance, SMA interface, and 18 GHz frequency limit. Verify that alternative components meet the same 2W power and VSWR specifications.
