HMC474SC70ETR

Overview

The HMC474SC70ETR is a general-purpose SiGe HBT gain block MMIC amplifier from Analog Devices Inc. It operates from DC to 6 GHz in an SC-70-6 surface-mount package. Key electrical parameters include a typical gain of 19 dB, a noise figure of 2.5 dB, and a P1dB compression point of 12 dBm. The device requires a 5 V supply with a current draw of 35 mA. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes Silicon Germanium (SiGe) Heterojunction Bipolar Transistor technology for high performance.
• Provides broadband amplification covering DC to 6 GHz frequency range.
• Designed for surface-mount integration in compact form factors.

Applications

• WiMAX wireless communication systems
• WiBro wireless communication systems
• General purpose RF signal conditioning

Procurement Notes

Verify the specific suffix 'ETR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the SC-70-6 footprint matches the target PCB layout dimensions. Ensure the 5V supply voltage aligns with system power rails before finalizing procurement specifications.

Selection Notes

Select this component when a wideband DC-to-6 GHz response is required within a minimal SC-70-6 footprint. The SiGe HBT technology offers a balance of gain and noise performance suitable for intermediate frequency stages. Consider the 35 mA supply current against total system power budgets during the design phase.

Part Context

This part belongs to the HMC474 series of SiGe HBT gain block amplifiers manufactured by Analog Devices Inc. The series is characterized by its broad bandwidth and low profile, making it suitable for modern wireless infrastructure where space constraints are critical. The SC-70-6 package variant ensures compatibility with standard SMT manufacturing lines.
