AMMC-6650-W10

Overview

The AMMC-6650-W10 is a voltage-controlled variable attenuator module manufactured by Broadcom Limited. It operates within a frequency range of DC to 40 GHz and provides a nominal attenuation of 20 dB. The component is designed for a system impedance of 50 Ohms. This monolithic microwave integrated circuit (MMIC) utilizes gallium arsenide technology to deliver precise signal control in high-frequency applications.

Feature Summary

• Voltage-controlled variable attenuation capability
• Wideband operation from DC to 40 GHz
• Monolithic MMIC construction

Applications

• Test and measurement equipment
• Wireless communication systems
• Microwave instrumentation

Procurement Notes

Verify the specific suffix W10 against official Broadcom documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with 50 Ohm system designs. Confirm that the DC-40 GHz operational range meets application requirements. Check for any RoHS or REACH compliance declarations in the latest datasheet revision.

Selection Notes

Select this component when a wideband, voltage-controlled attenuator is required up to 40 GHz. The 20 dB range suits applications needing significant signal reduction. Consider the 50 Ohm impedance match for standard RF interfaces. Evaluate thermal management needs as the device operates at microwave frequencies.

Part Context

This part belongs to the AMMC-6650 series of variable attenuators from Broadcom. These devices are designed for high-performance RF applications requiring precise attenuation control over a broad frequency spectrum. The series typically integrates control circuitry and attenuation elements into a compact MMIC form factor.

Replacement Considerations

Consult official Broadcom substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before replacing. Generic substitutes may not match the 40 GHz performance specification.
