AMMC-6640-W50

Overview

The AMMC-6640-W50 is a monolithic microwave integrated circuit (MMIC) attenuator module manufactured by Broadcom Limited. It provides a fixed attenuation value of 20 dB with a characteristic impedance of 50 Ohms. The device operates across a frequency range from DC to 50 GHz, supporting high-frequency signal processing applications. It utilizes silicon technology and is designed for robust performance in wireless and RF systems.

Feature Summary

• Fixed 20 dB attenuation capability
• Wideband operation from DC to 50 GHz
• 50 Ohm impedance matching

Applications

• RF test and measurement equipment
• Wireless communication base stations
• Satellite communication systems

Procurement Notes

This component is listed as obsolete or discontinued by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors or surplus suppliers. Ensure that any available units are genuine Broadcom products and have been stored under appropriate conditions to maintain RF performance integrity before integration into designs.

Selection Notes

Select this part when a wideband, fixed 20 dB attenuation solution is required up to 50 GHz. Consider its MMIC form factor for compact PCB layouts. Verify that the 50 Ohm system impedance matches the surrounding circuitry. Due to its obsolete status, evaluate alternative components with similar frequency ranges and attenuation values for new production designs.

Part Context

The AMMC-6640 series belongs to Broadcom's portfolio of RF attenuator modules. These devices are engineered for precision signal control in high-frequency environments. The W50 suffix typically denotes specific packaging or tape-and-reel configurations within the product line, distinguishing it from other variants like the W10.
