HMC401QS16GE

Overview

The HMC401QS16GE is a GaAs InGaP HBT MMIC voltage-controlled oscillator (VCO) from Analog Devices. It integrates resonators and negative resistance devices within a single chip. The device operates in the 13.2 to 13.5 GHz frequency range. It features an integrated divide-by-8 circuit, providing a lower output frequency option. The component utilizes a QSOP-16 surface-mount package for compact integration.

Feature Summary

• Integrates resonator and negative resistance device on a single GaAs MMIC
• Includes built-in divide-by-8 functionality for flexible frequency synthesis
• Designed for high-frequency microwave applications

Applications

• Microwave communication systems
• Frequency synthesizer designs
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance status according to the manufacturer's official documentation. Confirm the QSOP-16 package dimensions match the target PCB footprint. Ensure the operating temperature range aligns with the system environment requirements before finalizing the procurement order.

Selection Notes

Select this component when a fixed frequency VCO with integrated division is required at 13.2-13.5 GHz. The integrated design reduces external component count compared to discrete solutions. Consider the power supply requirements and tuning voltage characteristics specified in the datasheet for proper biasing and performance optimization.

Part Context

This part belongs to the HMC series of monolithic microwave integrated circuits. It represents a specialized solution for high-frequency generation where size and integration are critical. The technology leverages GaAs InGaP HBT processes for reliable microwave performance.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if alternative VCOs offer wider tuning ranges or different output frequencies if system flexibility is needed.
