HMC494LP3E

Overview

The HMC494LP3E is a low noise Divide-by-8 static divider utilizing InGaP GaAs HBT technology. It operates from DC to 18 GHz with a divide ratio of 8. The device requires a supply voltage between 4.75 V and 5.25 V, drawing approximately 103 mA. It features an output power of -4 dBm and is housed in a leadless 3x3 mm QFN-16 surface mount package.

Feature Summary

• Implements divide-by-8 frequency division using InGaP GaAs HBT technology
• Operates across a wide frequency range from DC to 18 GHz
• Designed for low noise performance in high-frequency applications

Applications

• VSAT systems
• Point-to-point microwave links
• Frequency synthesizers

Procurement Notes

Verify the specific suffix (e.g., LP3E) against official Analog Devices documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering part number matches the required tape and reel or cut tape configuration specified in the current datasheet revision.

Selection Notes

Select this component when a divide-by-8 function is required up to 18 GHz. Compare with the HMC493LP3E if a divide-by-4 ratio is needed instead. Ensure the design accommodates the 103 mA current draw and -4 dBm output level within the system budget.

Part Context

This component belongs to the HMC494 series of static dividers. It shares the same QFN-16 package and operating temperature range (-40°C to +85°C) as related models like the HMC493LP3E, differing primarily in the division ratio and associated bias currents.

Replacement Considerations

HMC494LP3ETR is the tape and reel version of this component.
