HMC471MS8GE

Overview

The HMC471MS8GE is a dual SiGe HBT gain block amplifier from Analog Devices Inc., designed for RF and IF applications. It operates across a frequency range of 0 Hz to 5 GHz. The device provides a typical gain of 21 dB with a noise figure of 3.25 dB. Key performance metrics include a 1 dB compression point (P1dB) of 19 dBm and an output third-order intercept point (OIP3) of 34 dBm. It requires an operating supply voltage of 8 V and draws 80 mA of current. The component supports dual channels, features an input return loss of 12 dB, and dissipates up to 2.12 W of power. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture utilizing Silicon Germanium (SiGe) HBT technology for high-performance signal amplification.
• Wideband operational capability spanning DC to 5 GHz, suitable for versatile RF and IF stages.
• High linearity characteristics defined by significant output third-order intercept point and compression point values.

Applications

• Cellular, PCS, and 3G base station or mobile front-end circuits
• Fixed wireless access and WLAN infrastructure components
• CATV systems, cable modems, and direct broadcast satellite receivers

Procurement Notes

Verify the obsolete status and limited availability through official Analog Devices channels before design-in. Confirm that the 8-MSOP-EP package matches your PCB footprint requirements. Ensure thermal management strategies account for the specified power dissipation limits during operation. Cross-reference the specific suffix 'GE' against the latest datasheet to confirm pinout and electrical specifications remain unchanged. Validate compliance with RoHS directives relevant to your target market regulations.

Selection Notes

Select this component when dual-channel amplification is required within the 0-5 GHz spectrum. The SiGe technology offers a balance between low noise and high linearity. Consider the 8 V supply requirement and 80 mA current draw for power budgeting. The 8-MSOP-EP package is suitable for surface-mount assembly where space is constrained. Evaluate the 21 dB gain against system link budget requirements to determine if additional amplification stages are necessary.
