LCAT1002-20

Overview

The LCAT1002-20 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides an attenuation value of 20 dB with a power handling capacity of 2W. The device operates within a frequency range from DC to 3 GHz and maintains a system impedance of 50 Ohms. It utilizes SMA male-to-female connectors for inline integration. The unit features a brass body with gold plating and supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Provides precise 20 dB signal attenuation for RF applications
• Supports high power handling up to 2 Watts
• Operates effectively across a broad frequency spectrum from DC to 3 GHz
• Constructed with durable brass housing featuring gold plating

Applications

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

Procurement Notes

Verify the specific connector gender configuration (SMA Male to Female) matches the circuit design requirements before ordering. Confirm that the 2W power rating and 3 GHz frequency limit are sufficient for the intended application environment. Check for RoHS compliance status if environmental regulations apply to the deployment location. Ensure physical dimensions fit within the available space constraints of the assembly.

Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies up to 3 GHz. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. The 2W power rating makes it suitable for moderate power levels. Consider the brass construction for thermal stability and the wide operating temperature range for harsh environments. Verify that SMA connectors align with existing interface standards.

Part Context

This component belongs to the L-com passive series of connectorized attenuators. It is part of a broader family of RF components designed for signal management. The LCAT series typically offers various attenuation values and connector types to suit different RF system needs. This specific model focuses on providing stable performance in the lower microwave frequency range.

Replacement Considerations

Direct substitutes may include other 20 dB, 2W, 50 Ohm fixed attenuators with SMA connectors from manufacturers such as Pasternack or Cinch Connectivity Solutions. Ensure any replacement matches the exact frequency range and power handling specifications. Verify mechanical compatibility and connector gender orientation before swapping components.
