Attenuators Procurement Notes

Verify component status as obsolete before procurement planning. Confirm availability through secondary market distributors or surplus suppliers. Ensure compatibility with existing ECAD models if integrating into legacy designs. Check RoHS compliance details and humidity sensitivity handling requirements during storage and assembly processes.

Attenuators Selection Notes

Select this module when broadband attenuation up to 4 GHz is required with precise control. Consider the 6-MCOB package size for space-constrained PCB layouts. Evaluate thermal management needs given the 300 mW power rating and operating temperature range. Verify interface requirements against system impedance standards.

Attenuators Part Context

This component belongs to Broadcom's portfolio of RF attenuator modules, specifically designed for analog voltage-controlled attenuation. It represents a specialized solution for managing signal levels in high-frequency circuits where stability and linearity are critical parameters for system performance.

Attenuators Replacement Considerations

As the part status is listed as obsolete, direct substitutes may be limited. Review datasheets for alternative PIN diode attenuators from Broadcom or other manufacturers offering similar frequency ranges and attenuation values. Validate pinout and package dimensions for potential drop-in replacements.
