LCAT1001-03

Overview

The LCAT1001-03 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides an attenuation value of 3dB with a power rating of 2W and operates within a frequency range of DC to 3GHz. The component features a 50 Ohm impedance and utilizes SMA connectors, specifically configured as a male plug to female jack interface. Constructed with a stainless steel body, it ensures durability and consistent performance across various environmental conditions.

Feature Summary

• Provides precise 3dB signal attenuation for RF applications
• Features robust stainless steel construction for mechanical stability
• Utilizes standard SMA male-to-female connector interface

Applications

• RF signal level adjustment in communication systems
• Impedance matching and signal conditioning in test equipment
• Component protection in high-power transmission lines

Procurement Notes

Verify the specific connector gender configuration and physical dimensions against design requirements before procurement. Confirm that the operating frequency range up to 3GHz aligns with system specifications. Ensure compatibility with existing SMA interfaces and validate power handling capabilities for the intended application environment.

Selection Notes

Select this model when a 3dB attenuation value is required within the 3GHz bandwidth. Consider the 2W power rating for thermal management needs. The SMA interface dictates mating connector types. Stainless steel housing offers superior durability compared to plated alternatives in harsh environments.

Part Context

This component belongs to the L-com passive attenuator series, which includes various attenuation values and connector types. It shares the same structural design language and material specifications as other models in the family, differing primarily in attenuation value and frequency response characteristics defined by its internal resistive network.

Replacement Considerations

Equivalent parts include LCAT1001-07 (7dB) or LCAT1001-10 (10dB) if different attenuation levels are acceptable. Other manufacturers offering SMA 3dB 2W attenuators may serve as substitutes provided VSWR and frequency specs match.
