HMC398QS16GE

Overview

The HMC398QS16GE is a single-chip GaAs InGaP HBT MMIC voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It integrates an active resonator and is housed in a 16-lead QSOP package. The component operates within the frequency range of 2.5 GHz to 4.0 GHz, providing a tuning range of 1.5 GHz. It functions as an x8 frequency divider with an output power level of +7 dBm. The device requires a supply voltage of 5 V and consumes a maximum current of 100 mA.

Feature Summary

• Integrates an active resonator for compact design
• Provides high-output power at the divided frequency
• Utilizes robust GaAs InGaP HBT technology

Applications

• Wireless communication systems requiring frequency synthesis
• Local oscillator sources in RF transceivers
• Test and measurement equipment needing stable signal generation

Procurement Notes

Verify the specific suffix 'E' against official Analog Devices documentation to confirm RoHS compliance status and pinout configuration. Ensure the procurement channel provides valid traceability for this obsolete or limited-lifecycle component. Cross-reference the datasheet revision date to guarantee compatibility with existing circuit designs.

Selection Notes

Select this component when a monolithic solution combining VCO and frequency division is required. It is suitable for applications demanding a wide tuning range without external resonators. Consider the 16-QSOP package constraints and thermal dissipation requirements relative to the 5 V supply operation.

Part Context

This part belongs to the HMC series of microwave monolithic integrated circuits from Analog Devices. It represents a specialized RF solution designed to simplify system architecture by integrating multiple functions into a single chip, reducing board space and component count compared to discrete implementations.

Replacement Considerations
