AMMP-6640-BLKG

Overview

The AMMP-6640-BLKG is a monolithic microwave integrated circuit (MMIC) variable attenuator manufactured by Broadcom Limited. It operates across a frequency range of 0 Hz to 40 GHz with a nominal impedance of 50 Ohms. The device provides an attenuation range from 2.5 dB to 28 dB. It is housed in an 8-SMD, no-lead package and is classified as an obsolete product.

Feature Summary

• Wideband operation spanning DC to 40 GHz
• Monolithic microwave integrated circuit construction
• Variable attenuation control capability

Applications

• Test and measurement equipment requiring high-frequency signal adjustment
• Wireless communication systems operating in millimeter-wave bands
• Radar systems utilizing wideband signal processing

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to surplus or secondary market channels. Verify authenticity and storage history carefully due to potential age-related degradation. Confirm lead times with suppliers as stock levels fluctuate unpredictably for discontinued items.

Selection Notes

Select this part only if the specific 0-40 GHz bandwidth and 8-SMD form factor are required. Ensure the system design accommodates the maximum 28 dB attenuation range. Consider that the obsolete status may limit long-term supply continuity. Evaluate alternative components if future production stability is a priority.

Part Context

The AMMP-6640 series belongs to Broadcom's portfolio of RF and microwave MMICs designed for high-frequency applications. These devices integrate passive and active components on a single substrate to provide precise signal control. The BLKG suffix typically denotes a specific tape-and-reel packaging configuration for surface-mount assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements must be identified through engineering evaluation of equivalent electrical specifications and pin compatibility.
