HMC578LC3BTR-R5

Overview

The HMC578LC3BTR-R5 is a GaAs MMIC frequency multiplier designed for surface-mount applications. It operates as an x2 active multiplier with an output frequency range of 24 GHz to 33 GHz. The device requires a supply voltage between 4.5 V and 5.5 V and draws approximately 82 mA of operating current. It is housed in a compact QFN-12 package measuring 3x3 mm, suitable for high-frequency RF systems requiring efficient frequency conversion.

Feature Summary

• Utilizes Gallium Arsenide (GaAs) monolithic microwave integrated circuit technology for high-performance RF operation.
• Functions as an active x2 frequency multiplier to double the input signal frequency within the specified band.
• Integrated into a small form-factor QFN-12 surface-mount package for space-constrained PCB designs.

Applications

• DBS (Direct Broadcast Satellite) receiver front-ends
• VSAT (Very Small Aperture Terminal) communication systems
• Point-to-point microwave radio links

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions meet JESD22-A113 standards to prevent damage. Review the latest datasheet for handling precautions specific to GaAs MMICs. Validate that the QFN-12 footprint matches your PCB layout requirements before procurement.

Selection Notes

Select this component when a fixed x2 multiplication ratio is required in the Ka-band spectrum. Compare against other HMC576 series variants if different frequency ranges are needed. Consider thermal management capabilities due to the low-power dissipation profile. Evaluate integration complexity relative to discrete multiplier solutions. Ensure system LO sources align with the input frequency requirements for optimal harmonic generation.

Part Context

This part belongs to the HMC578G family of RF multipliers from Analog Devices. It shares architectural similarities with the HMC576 series but targets higher frequency outputs. The LC3B suffix indicates a specific lead frame and package configuration optimized for SMT processes. These components are commonly used in wireless infrastructure and satellite communications where size and linearity are critical.

Replacement Considerations

HMC576LC3BTR-R5 serves as a functional substitute for lower frequency applications (18-29 GHz). Verify input frequency compatibility as the HMC578 is optimized for higher bands. Pinout configurations are generally compatible within the LC3B family, but electrical parameters differ significantly. Consult official substitution guides for detailed performance trade-offs.
