HMC479MP86E

Overview

The HMC479MP86E is a SiGe Heterojunction Bipolar Transistor (HBT) gain block MMIC amplifier designed for surface-mount applications. It operates from DC to 5 GHz, providing a typical gain of 14.5 dB with a noise figure of 4 dB. The device requires an operating supply current of 72 mA and functions within a voltage range of 3V. Packaged in the SOT-86 micro-package, it is optimized for cellular and CATV systems where low power consumption and compact form factors are critical.

Feature Summary

• Utilizes SiGe HBT technology for high-performance RF amplification
• Operates across a wide frequency range from DC to 5 GHz
• Designed for low-power applications with minimal supply current requirements
• Compact SOT-86 package suitable for space-constrained mobile devices

Applications

• Cellular communication systems
• CATV signal distribution networks
• Low-noise front-end modules
• Wireless infrastructure components

Procurement Notes

Verify the specific suffix 'MP86E' against official Analog Devices documentation to confirm the exact pinout and electrical characteristics, as variations may exist between standard and E-rated versions. Ensure that the SOT-86 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compatibility with current design standards and regulatory compliance requirements for RF components.

Selection Notes

Select this component when a balance of moderate gain and low noise is required in the 5 GHz bandwidth. The 14.5 dB gain specification suits intermediate stages rather than final output drivers. Consider the 72 mA supply current constraint for battery-operated devices. The SOT-86 package offers a smaller footprint compared to traditional TO- packages, making it ideal for modern miniaturized electronics where board real estate is limited.

Part Context

This part belongs to the HMC47x series of SiGe HBT gain blocks from Analog Devices. It shares architectural similarities with the HMC478MP86E but extends the operational frequency up to 5 GHz. The series is characterized by robust performance in cellular and CATV environments, offering consistent gain flatness and linearity across the specified band while maintaining low power consumption profiles typical of SiGe technology.

Replacement Considerations

The HMC478MP86E is a documented related product covering DC to 4 GHz. Verify if the reduced upper frequency limit of the HMC478MP86E meets system requirements before substitution. Both parts share similar packaging and technology nodes, facilitating potential mechanical integration, but electrical parameters such as gain and noise figure must be re-evaluated for the new application context.
