HMC311SC70ETR

Overview

The HMC311SC70ETR is a GaAs InGaP HBT gain block MMIC amplifier from Analog Devices Inc., operating from DC to 8 GHz. It provides 15 dB of gain with a noise figure of 5 dB and an input return loss of 15 dB. The device operates on a 5 V supply, drawing 55 mA to 74 mA depending on the source. Key performance metrics include a P1dB compression point of 11 dBm to 15 dBm and an OIP3 of 30 dBm. Power dissipation is rated at 340 mW. It is housed in a compact SC-70-6 surface-mount package and functions as a single-channel RF amplifier suitable for general-purpose applications.

Feature Summary

• Utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) technology for robust signal amplification across a wide frequency range.
• Integrated into a standard SC-70-6 surface-mount package to facilitate space-constrained circuit board layouts.
• Designed as a general-purpose gain block amplifier offering consistent performance from direct current up to 8 GHz.

Applications

• GPS receiver front-end stages
• General-purpose RF signal chain components
• Wireless communication systems requiring broadband amplification

Procurement Notes

Verify component authenticity through authorized channels due to the obsolete lifecycle status. Confirm specific electrical parameters against the official datasheet, as values such as P1dB and supply current may vary slightly between documentation sources. Ensure compatibility with existing PCB footprints and thermal management requirements before integration.

Selection Notes

Select this component for designs requiring a compact, broadband amplifier with moderate gain and low noise characteristics. Consider the SC-70-6 package size for space-sensitive applications. Evaluate the 5 V supply requirement and current consumption against system power budgets. Verify that the 8 GHz upper frequency limit meets the operational bandwidth needs of the target application.
