HMC492LP3

Overview

The HMC492LP3 is a GaAs InGaP HBT MMIC prescaler designed for divide-by-2 applications. It operates from DC to 18 GHz with an output power of -4 dBm. The device requires a single +5 V supply and draws 78 mA of operating current. It is housed in a compact 3x3 mm QFN-16 surface-mount package. The unit weight is approximately 57.1 mg. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Ultra-low single-sideband phase noise performance
• Very wide bandwidth coverage from DC to 18 GHz
• Single positive DC supply operation

Applications

• High-frequency frequency synthesis systems
• Microwave test and measurement equipment
• Wireless communication infrastructure components

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix matches the required RoHS compliance status, as variations exist between standard and lead-free versions. Check current availability status, as this part may be subject to limited supply conditions or discontinuation notices depending on the region and date of inquiry.

Selection Notes

Select this component when a high-speed divide-by-2 function is required up to 18 GHz. Ensure the design accommodates the 78 mA current draw and +5 V supply requirement. The QFN-16 package necessitates appropriate thermal management and PCB layout considerations for the exposed pad. Verify that the input signal levels are compatible with the MMIC interface specifications.

Part Context

This prescaler belongs to the HMC492 series of RF integrated circuits manufactured by Analog Devices. It utilizes GaAs InGaP HBT technology to achieve high-frequency performance in a small form factor. The series is intended for applications requiring precise frequency division in microwave and millimeter-wave systems.

Replacement Considerations

The HMC492LP3E is a verified alternative within the same family, offering identical electrical characteristics but potentially differing in environmental compliance or packaging details. Cross-reference datasheets to confirm pinout and parameter equivalence before substitution.
