HMC985LP4KETR

Overview

The HMC985LP4KETR is a monolithic microwave integrated circuit (MMIC) variable attenuator manufactured by Analog Devices Inc. It operates within the frequency range of 10 GHz to 40 GHz and provides a total attenuation value of 40 dB. The device features a 24-lead Very Low Profile Quad Flat No-Lead (VQFN) package, designed for surface-mount applications. It utilizes silicon technology and maintains a standard impedance of 50 Ohms. This component is categorized under wireless and RF integrated circuits, suitable for high-frequency signal processing tasks requiring precise attenuation control.

Feature Summary

Provides continuous variable attenuation across a wide millimeter-wave frequency spectrum
Integrated MMIC design ensures compact footprint and reliable performance
Utilizes low-profile surface-mount packaging for efficient board space utilization

Applications

Embedded electronics systems
Industrial equipment signal conditioning
Maintenance and test instrumentation

Procurement Notes

Verify current availability status as supply may be limited or subject to factory special order constraints. Confirm RoHS compliance details through official documentation before integration. Ensure ordering suffix matches required packaging format. Cross-reference manufacturer part number with distributor listings to confirm authenticity and revision level prior to procurement.

Selection Notes

Select this component when fixed attenuation values are insufficient for system calibration needs. Consider the 10 GHz to 40 GHz operational range against specific application bandwidth requirements. Evaluate the 24-lead VQFN package dimensions for compatibility with existing PCB layout constraints. Assess thermal management capabilities relative to expected power dissipation levels in the target environment.

Part Context

This component belongs to the HMC985 series of RF attenuators from Analog Devices. It is classified within the Wireless & RF Integrated Circuits subcategory. The device represents a silicon-based solution for high-frequency signal control, distinct from lower-frequency mixer or amplifier variants within the broader product portfolio.
