HMC543ALC4B

Overview

The HMC543ALC4B is a 4-bit digital phase shifter manufactured by Analog Devices Inc. using Silicon technology. It operates within the 8 to 12 GHz frequency range, providing continuous phase coverage from 0 to 360 degrees. The device features a least significant bit (LSB) resolution of 22.5 degrees. It is housed in a compact LC4B package and is designed for surface-mount installation.

Feature Summary

• Provides precise 4-bit digital phase control across the full 360-degree spectrum
• Operates effectively within the Ku-band frequency range of 8 to 12 GHz
• Utilizes silicon MMIC technology for reliable signal processing

Applications

• Phased array antenna systems
• Wireless communication infrastructure
• Test and measurement equipment

Procurement Notes

Verify the specific suffix LC4B to confirm the package type and pinout configuration. Ensure compatibility with the required 8-12 GHz operational bandwidth. Confirm that the silicon-based construction meets the thermal and environmental specifications of the target application environment before integration.

Selection Notes

Select this component when a compact, digitally controlled phase shift solution is required for Ku-band applications. The 22.5-degree LSB step size offers sufficient resolution for many beamforming networks. Consider the LC4B package dimensions for PCB layout constraints and verify interface voltage levels against system requirements.

Part Context

This part belongs to the Hittite (now Analog Devices) HMC543 series of digital phase shifters. These components are engineered for high-performance RF applications requiring stable phase characteristics over wide bandwidths. The series is widely utilized in modern radar and satellite communication systems where precise signal alignment is critical.

Replacement Considerations

Check for direct equivalents such as the HMC543ALC4BTR variant if reel packaging is preferred. Verify functional compatibility with other 4-bit phase shifters in the same frequency band, ensuring pin-to-pin matching if board space is constrained.
