LCAT7609-10

Overview

The LCAT7609-10 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in radio frequency circuits. It provides a nominal attenuation of 10 dB with a characteristic impedance of 50 Ohms. The device operates over a frequency range from DC to 3 GHz and can handle a maximum power rating of 2 Watts. It features TNC connectors, specifically a male plug on one end and a female jack on the other, facilitating inline integration into coaxial systems.

Feature Summary

• Provides precise 10 dB signal attenuation for RF applications
• Operates reliably within a frequency range up to 3 GHz
• Supports continuous power loads of up to 2 Watts
• Utilizes durable brass construction with TNC interface compatibility

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment setups
• Antenna system impedance matching networks
• Receiver input protection stages

Procurement Notes

Verify that the specific part number matches the required 10 dB attenuation value and 50 Ohm impedance specifications. Confirm connector gender configuration aligns with existing cable assemblies. Ensure operational frequency requirements do not exceed the 3 GHz upper limit. Check power handling capabilities against peak signal levels in the target circuit to prevent thermal damage during procurement validation.

Selection Notes

Select this component when a fixed 10 dB loss is required between DC and 3 GHz frequencies. Choose based on the need for robust 2W power handling in a compact inline module format. Consider the TNC interface type for compatibility with standard coaxial connections. Evaluate environmental factors if operating conditions require specific material durability beyond standard brass construction.

Part Context

This model belongs to the LCA series of fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and TNC connectivity. These components are engineered for stable performance across defined frequency bands, serving as essential passive elements in RF signal chain management and calibration procedures.

Replacement Considerations

Public confirmed substitute part numbers include FMAT7609-10, PE7609-10, and R414503000. Verify that any replacement maintains identical 10 dB attenuation, 50 Ohm impedance, and 2W power rating. Ensure connector types match the original TNC male-to-female configuration before substitution.
