Overview
The LCAT7467-20 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in coaxial systems. It provides a nominal attenuation of 20 dB with a tolerance of ±1 dB. The device operates across a frequency range from DC to 12 GHz and maintains a characteristic impedance of 50 Ohms. It supports a maximum continuous wave power handling of 2 Watts. The unit features SMA connectors, specifically an SMA male plug on one end and an SMA female jack on the other, facilitating direct inline integration into RF test setups.
Feature Summary
- Provides precise 20 dB signal attenuation within a wide DC to 12 GHz operational bandwidth
- Features robust SMA male-to-female connector configuration for secure inline mounting
- Capable of dissipating up to 2 Watts of continuous wave power without performance degradation
- Maintains low voltage standing wave ratio (VSWR) of 1.35:1 for minimal signal reflection
Applications
- RF test and measurement instrumentation signal conditioning
- Wireless communication system component protection
- Laboratory circuit analysis and characterization
- Signal level adjustment in high-frequency transmission lines
Procurement Notes
Verify that the specific part number matches the required 20 dB attenuation value and SMA connector polarity. Confirm that the operating environment does not exceed the 2 Watt power rating or 12 GHz frequency limit. Ensure compatibility with existing SMA interfaces in the signal chain to prevent impedance mismatches or connection failures during installation.
Selection Notes
Select this model when a fixed 20 dB reduction is required for signals up to 12 GHz. Consider the 2 Watt power handling capability relative to the source output. Evaluate the SMA interface requirements against the system's connector types. Compare VSWR specifications against system sensitivity requirements to ensure signal integrity is maintained throughout the frequency band.
Part Context
This component belongs to the LCAT series of fixed attenuators from L-com, which offers various attenuation levels and connector configurations. The series is engineered for consistent performance in RF applications requiring stable signal reduction. The LCAT7467-20 specifically addresses needs for moderate signal loss in high-frequency environments using standard coaxial interfaces.
Replacement Considerations
Substitute only with components explicitly documented as electrically equivalent in terms of attenuation value, frequency range, power rating, and connector type. Verify that any alternative part meets the same 50 Ohm impedance and SMA interface specifications to maintain system compatibility.
