HMC644ALC5

Overview

The HMC644ALC5 is a GaAs MMIC 5-bit digital phase shifter rated for the 15 to 18.5 GHz frequency range. It provides 360 degrees of total phase coverage with a least significant bit (LSB) resolution of 11.25 degrees. The device features an RMS phase error of 3.5 degrees and insertion loss characteristics optimized for high-performance applications.

Feature Summary

• Highly integrated GaAs MMIC design for microwave applications
• Provides full 360-degree phase coverage across five discrete bits
• Low RMS phase error ensures precise signal control

Applications

• Phased array radar systems
• Microwave communication links
• Satellite ground stations

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Check for End-of-Life notifications or discontinuance alerts, as supply availability may be restricted. Ensure handling procedures meet SMD/SMT requirements for die-level components.

Selection Notes

Select this component when operating within the 15-18.5 GHz band requiring precise digital phase control. Consider the 11.25-degree LSB resolution for beamforming accuracy. Evaluate thermal management needs due to the die package format. Compare against alternative series like HMC642 if lower frequency operation is required.

Part Context
