LCAT1002-05

Overview

The LCAT1002-05 is a fixed RF attenuator from the L-com LCAT series, designed for interconnect applications. It provides a nominal attenuation of 5 dB with an accuracy of ±0.5 dB. The device operates over a frequency range from DC to 3 GHz and maintains a characteristic impedance of 50 Ohms. It features SMA male-to-female connectors and supports a maximum input power of 2 Watts. The unit is constructed with a brass body finished in gold plating. Operating temperature specifications range from -55°C to +125°C, ensuring reliability in diverse environments.

Feature Summary

• Provides precise signal attenuation for RF circuits within specified frequency limits
• Features durable brass construction with gold plating for corrosion resistance
• Supports high-power handling capabilities up to 2 Watts continuously

Applications

• RF test and measurement equipment signal conditioning
• Wireless communication system component integration
• Laboratory instrumentation signal level adjustment

Procurement Notes

Verify that the specific order matches the LCAT1002-05 designation to ensure correct 5 dB attenuation value. Confirm SMA connector gender configuration aligns with system requirements. Check datasheet for thermal management needs given the 2W power rating. Ensure environmental conditions fall within the specified -55°C to +125°C operating range for optimal performance.

Selection Notes

Select this model when a 5 dB reduction is required between DC and 3 GHz frequencies. Choose based on the need for SMA interface compatibility and 50 Ohm system matching. Consider the physical size and mounting style if space constraints exist. Evaluate the 2W power handling against peak signal levels to prevent damage.

Part Context

This component belongs to the LCAT series of passive connectorized attenuators manufactured by L-com. These devices are engineered for stable performance in RF and microwave applications. The series offers various attenuation values and connector types to suit different circuit needs. The LCAT1002-05 specifically addresses the need for moderate signal reduction in high-frequency systems.

Replacement Considerations

Direct parameter-equivalent substitutes include ATT-0313-07-BNC-10 from Cinch Connectivity Solutions, PE7437-7 from Pasternack, and R414407000 from Radiall USA, Inc. Verify connector type compatibility as some alternatives may use BNC interfaces instead of SMA.
