HMC474MP86ETR

Overview

The HMC474MP86ETR is a general-purpose SiGe Heterojunction Bipolar Transistor (HBT) gain block MMIC amplifier manufactured by Analog Devices Inc. It operates from DC to 6 GHz and is housed in a Micro-P surface-mount package. The device provides a typical gain of 15.5 dB with a noise figure of 3.4 dB. It features an 8 dBm P1dB output power and requires a supply voltage between 3V and 10V, drawing 25mA of current. Designed for cellular and CATV applications, it offers high linearity and stability within its specified frequency range.

Feature Summary

• Utilizes SiGe HBT technology for robust RF performance
• Integrated impedance matching for simplified circuit design
• Compact surface-mount packaging suitable for space-constrained layouts

Applications

• Cellular infrastructure systems
• CATV distribution networks
• General purpose RF signal amplification

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check for RoHS compliance status and lead times due to potential obsolescence. Request updated datasheets to ensure compatibility with current design requirements. Validate supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when a wideband DC-to-6GHz amplifier is required. Consider the 15.5dB gain and 3.4dB noise figure for low-noise front-end stages. Evaluate the 25mA supply current against system power budgets. Ensure the Micro-P package fits the available PCB footprint. Compare specifications against alternative gain blocks if higher output power is needed.

Part Context

This part belongs to the HMC474MP86 family of SiGe HBT gain block amplifiers. It is designed as a drop-in replacement for similar legacy components in RF designs. The series includes variants with different package options to suit various manufacturing needs. These amplifiers are widely used in communication systems requiring reliable broadband performance.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify that alternative parts meet the 6GHz frequency limit and 15.5dB gain requirement. Ensure supply voltage and current consumption remain compatible with existing bias circuits.
