HMC476MP86ETR

Overview

The HMC476MP86ETR is a SiGe HBT gain block amplifier from Analog Devices, operating from DC to 6 GHz. It delivers 20 dB of gain with a noise figure of 2.5 dB to 3.5 dB and an output P1dB of 12 dBm. Powered by a single 5 V supply drawing 35 mA, it features an OIP3 of 24 dBm and input return loss of 20 dB. The device dissipates 504 mW and operates within -40°C to +85°C. Packaged in a Micro-P (SOT-86) surface-mount format, it is designed for low-power RF applications.

Feature Summary

• Utilizes Silicon Germanium Heterojunction Bipolar Transistor technology for high-performance amplification
• Operates on a single positive voltage supply requiring minimal external bias components
• Provides linear amplification suitable for LO drivers or power amplifier stages

Applications

• Cellular communication systems
• CATV signal processing
• Local Oscillator (LO) driving
• Power Amplifier (PA) driver stages

Procurement Notes

Verify component authenticity through authorized channels as the HMC476MP86ETR is listed as obsolete by Analog Devices. Confirm package integrity upon receipt, as the Micro-P housing is sensitive to mechanical stress. Cross-reference datasheet revisions to ensure compatibility with current design requirements, noting that production may have ceased since March 2016.

Selection Notes

Select this component when a compact, low-noise gain stage is required up to 6 GHz. It is appropriate for designs needing 20 dB gain with minimal power consumption. Consider the Micro-P package constraints for PCB layout. Evaluate thermal dissipation capabilities given the 504 mW power rating in small form factor applications.

Part Context

This part belongs to the HMC476 family of MMIC amplifiers. It shares functional similarities with the HMC476SC70ETR but differs in packaging and specific electrical characteristics. The HMC476 series is engineered for wireless infrastructure and mobile devices, offering integrated solutions for RF signal chain management without extensive external matching networks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, engineers should consult Analog Devices for potential drop-in replacements or updated series recommendations.
