HMC478MP86E

Overview

The HMC478MP86E is a SiGe HBT Gain Block MMIC amplifier covering DC to 4 GHz. It provides 22 dB of gain with a noise figure of 2.5 dB. The device operates on a 5 V supply, drawing 62 mA of current. Maximum power dissipation is rated at 583 mW. It is housed in an SOT-86 package and functions as a general-purpose RF/IF gain block or LO/PA driver.

Feature Summary

• Utilizes SiGe Heterojunction Bipolar Transistor technology for high-performance amplification
• Designed as a general-purpose RF and IF gain block
• Suitable for local oscillator or power amplifier driving applications

Applications

• Cellular / PCS / 3G systems
• Fixed Wireless & WLAN infrastructure
• CATV, Cable Modem & DBS equipment

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official documentation to confirm environmental compliance status and exact pinout configuration. Ensure the SOT-86 package dimensions match the design footprint requirements. Cross-reference the 5 V supply voltage and 62 mA current draw with the system power budget before finalizing procurement.

Selection Notes

Select this component when a wideband DC to 4 GHz response is required with moderate gain. The low noise figure of 2.5 dB makes it suitable for sensitive front-end stages. Consider the SOT-86 package size for space-constrained layouts. Verify thermal management capabilities given the 583 mW maximum power dissipation rating under operating conditions.
