HMC533LP4ETR

Overview

The HMC533LP4ETR is a surface-mount voltage-controlled oscillator (VCO) from Analog Devices, designed for high-frequency applications. It operates within a frequency range of 23.8 GHz to 24.8 GHz. The device features dual outputs, including a standard output and a divide-by-16 output. It is housed in a compact 24-lead QFN package measuring 4 mm by 4 mm. This component integrates the VCO core with necessary buffer amplifiers to ensure signal integrity and stability across its specified operating temperature range.

Feature Summary

• Integrates a high-frequency VCO core with integrated buffer amplifiers for stable signal generation.
• Provides dual output configurations, including a standard fundamental frequency output and a divided-by-16 harmonic output.
• Utilizes a compact surface-mount QFN package design suitable for dense PCB layouts.

Applications

• High-frequency communication systems requiring precise frequency synthesis
• Test and measurement equipment needing stable microwave signals
• Radar subsystems utilizing millimeter-wave frequencies

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the supply chain source provides valid traceability documentation. Check for any recent product change notifications that might affect pin compatibility or electrical characteristics. Ensure storage conditions meet the moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when a fixed frequency range between 23.8 GHz and 24.8 GHz is required. The integrated divide-by-16 output is advantageous for systems needing lower frequency reference signals without external dividers. Consider the thermal management capabilities of the QFN package in high-power environments. Evaluate the phase noise performance specifications against system sensitivity requirements before finalizing the design.
