Procurement Notes

Verify the specific part number LCAT7437-9 against manufacturer documentation to confirm the 9dB attenuation value and 50 Ohm impedance. Ensure compatibility with existing BNC connector interfaces and check that the 2W power rating meets system requirements. Confirm the operating temperature range aligns with environmental conditions before procurement.

Selection Notes

Select this component when a fixed 9dB reduction is required at frequencies up to 4 GHz. Consider the 2W power handling capability and brass construction for durability. Ensure the BNC connector type matches the system's male/female port configuration. Verify impedance matching to prevent signal reflection in 50 Ohm systems.

Part Context

This component belongs to L-com's passive connectorized attenuator series. It is part of a family offering various attenuation values, such as 3dB, 15dB, and 30dB models, all sharing similar BNC connector styles and power ratings.
