HMC478MP86ETR

Overview

The HMC478MP86ETR is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier manufactured by Analog Devices Inc. It covers a frequency range from DC to 4 GHz. The device operates with a supply voltage of 6V to 12V and draws a supply current of 62mA. It features a gain of 20dB, a P1dB of 20dBm, and a noise figure ranging from 3.5dB to 4.5dB. The component is housed in a Micro-P package (SOT-86) and is designed for surface mount installation.

Feature Summary

• Utilizes SiGe HBT technology for high-performance RF amplification
• Provides wideband coverage from DC to 4 GHz
• Integrated gain block design simplifies circuit implementation

Applications

• General purpose RF signal chain applications
• GPS receiver front-end stages

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing replacements, as manufacturing updates may occur. Confirm that the intended application environment supports the specified supply voltage range and thermal requirements. Check for any product change notices or end-of-life announcements prior to finalizing procurement plans to ensure long-term availability compatibility.

Selection Notes

Select this component for designs requiring a compact, high-gain amplifier with low noise characteristics across a broad DC-to-4GHz spectrum. Ensure the system power budget accommodates the 62mA supply current and that the PCB layout supports the Micro-P surface mount footprint. Consider the 20dBm P1dB specification when determining linearity requirements for the target signal path.

Part Context
