HMC493LP3ETR

Overview

The HMC493LP3ETR is a GaAs InGaP HBT divide-by-4 prescaler from Analog Devices Inc., operating from DC to 18 GHz. It features a QFN-16 package and requires a 5 V supply with 96 mA current draw. The device delivers -4 dBm output power and supports SMD/SMT mounting within a -40°C to +85°C temperature range.

Feature Summary

• Divides input frequency by four using InGaP HBT technology
• Operates across a wide bandwidth from DC to 18 GHz
• Integrated in a compact surface-mount QFN-16 package

Applications

• VSAT systems
• Frequency synthesis circuits
• RF test and measurement equipment

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as documentation may vary. Ensure supply chain stability for production planning given potential restricted distribution. Validate datasheet revisions before final design integration.

Selection Notes

Select this component for high-frequency division applications requiring DC coupling. The InGaP HBT process offers robust performance up to 18 GHz. Consider the 5 V single-supply requirement and 96 mA consumption during power budgeting. The QFN-16 footprint suits space-constrained PCB layouts.

Part Context

Part of the HMC493 series, this prescaler complements other RF ICs like the HMC500 modulator and HMC903 LNA. It serves as a critical frequency reduction stage in high-speed communication architectures, enabling lower-frequency processing of millimeter-wave signals.

Replacement Considerations

No public confirmed substitute part numbers are available.
