HMC649LP6E

Overview

The HMC649LP6E is a GaAs MMIC 6-bit digital phase shifter designed for operation within the 3 GHz to 6 GHz frequency range. It provides full 360-degree phase coverage with a least significant bit (LSB) resolution of 5.625 degrees. The component utilizes a surface-mount 28-VQFN package with an exposed pad, suitable for radar and wireless applications.

Feature Summary

• Provides 360-degree continuous phase coverage across the specified frequency band
• Utilizes GaAs MMIC technology for high-performance RF signal processing
• Features 6-bit digital control interface for precise phase adjustment

Applications

• Radar systems
• Wireless communication infrastructure
• Beamforming networks

Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation before procurement. Confirm that the 28-VQFN footprint matches the design requirements. Ensure compatibility with the required control voltage levels for the digital inputs. Check for any recent lifecycle updates or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a wideband phase shifting capability between 3 GHz and 6 GHz is required. The 6-bit resolution offers a balance between control precision and complexity. Consider the thermal performance of the exposed pad QFN package for heat dissipation in dense PCB layouts.
