LCAT1000-01

Overview

The LCAT1000-01 is an RF fixed attenuator manufactured by L-com, designed for coaxial in-line applications. It features SMA male to SMA female connectors and provides a nominal attenuation of 1 dB with a tolerance of ±0.5 dB. The device operates within a frequency range of DC to 6 GHz and supports a maximum continuous wave power of 2 Watts. It maintains a voltage standing wave ratio (VSWR) of less than 1.2:1 and utilizes a 50 Ohm impedance system. Constructed from stainless steel with a hex nut on the body, it ensures reliable signal management in high-frequency circuits.

Feature Summary

• Coaxial in-line design with SMA male to SMA female interface
• Stainless steel construction with hex nut for secure mounting
• Fixed 1 dB attenuation with ±0.5 dB tolerance
• Operates up to 6 GHz with 2W maximum power handling

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Signal conditioning in microwave circuits
• Attenuation in antenna feed lines

Procurement Notes

Verify the specific part number LCAT1000-01 against official L-com documentation to confirm SMA male-to-female configuration and 1 dB attenuation value. Ensure compatibility with 50 Ohm systems and 6 GHz frequency limits. Check for RoHS compliance status as indicated in manufacturer datasheets. Confirm physical dimensions and connector gender before integration into existing assemblies.

Selection Notes

Select this component when a precise 1 dB reduction is required in RF paths operating below 6 GHz. The SMA interface suits standard laboratory and industrial setups. Consider the 2W power rating for thermal management in high-power applications. Stainless steel body offers durability compared to plated alternatives. Verify VSWR requirements against system specifications to ensure minimal signal reflection.

Part Context

The LCAT1000 series represents L-com's line of fixed RF attenuators. The LCAT1000-01 specifically denotes the 1 dB variant within this family. These components are engineered for consistent performance across wide bandwidths. The series includes various attenuation values, all sharing similar mechanical designs with SMA connectors. This model is part of a broader portfolio addressing diverse signal attenuation needs in RF engineering.

Replacement Considerations

Direct substitutes include other LCAT1000 series variants with different attenuation values if the dB requirement changes. Cross-brand equivalents must match SMA male-to-female interfaces, 50 Ohm impedance, and 6 GHz frequency range. Verify power handling capabilities and VSWR specifications to ensure functional parity without circuit modification.
