LCAT7094-15

Overview

The LCAT7094-15 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a precise attenuation value of 15 dB with a tolerance typically within standard specifications for this class. The component operates across a frequency range from 0 Hz to 18 GHz, ensuring broad utility in microwave applications. It features a 50 Ohm impedance match and supports a maximum continuous wave power handling capacity of 2 Watts. The physical interface utilizes N-type connectors, specifically configured as an in-line module with male-to-female connections. The housing is constructed from passivated stainless steel, offering durability and environmental resistance suitable for demanding RF environments.

Feature Summary

• Provides stable 15 dB attenuation for signal level control
• Operates effectively from DC up to 18 GHz frequency range
• Features robust 2W power handling capability
• Constructed with passivated stainless steel body for corrosion resistance

Applications

• RF test and measurement equipment signal conditioning
• Microwave communication system power reduction
• Antenna feed line attenuation matching
• Laboratory benchtop circuit protection

Procurement Notes

Verify the specific datasheet version provided by L-com or authorized distributors to confirm exact VSWR values and tolerance bands, as these parameters can vary slightly between production batches. Ensure that the connector gender configuration matches the system requirements, as N-type interfaces are polarized. Confirm thermal management needs, as continuous operation at 2W may require adequate heat dissipation depending on ambient conditions. Cross-reference part numbers carefully to avoid confusion with similar models like the LCAT7094-10 which offers different attenuation levels.

Selection Notes

Select the LCAT7094-15 when a fixed 15 dB reduction is required in systems operating up to 18 GHz. This model is appropriate for applications needing reliable power handling of 2W without active components. Consider the N-type connector interface compatibility with existing cabling infrastructure. The stainless steel construction makes it suitable for environments where mechanical strength and corrosion resistance are prioritized over weight savings. Evaluate if the fixed attenuation value meets the specific link budget requirements compared to variable alternatives.

Part Context

This component belongs to L-com's series of fixed coaxial attenuators, which are passive devices used to reduce signal amplitude without distortion. These units are integral to maintaining signal integrity in high-frequency circuits by preventing receiver overload or adjusting transmission levels. The LCAT7094 series generally shares similar form factors and connector types, differing primarily in their attenuation values and specific performance metrics tailored for various RF bandwidths and power levels.

Replacement Considerations

Direct substitutes include other 15 dB fixed attenuators with N-type connectors and comparable power ratings, such as those from manufacturers like Mini-Circuits or Pasternack, provided they meet the 18 GHz frequency limit. Verify that replacement parts maintain the same 50 Ohm impedance and physical dimensions for seamless integration. Ensure that any alternative component offers equivalent VSWR performance to preserve signal quality in sensitive RF paths.
