HMC311LP3E

Overview

The HMC311LP3E is a GaAs InGaP HBT Gain Block MMIC amplifier from Analog Devices Inc., designed for surface-mount applications. It operates across a frequency range of DC to 6 GHz with a typical gain of 14.5 dB and a noise figure of 4.5 dB. The device requires a 5 V supply voltage and draws 55 mA of current. Key performance metrics include a P1dB compression point of 15.5 dBm, an OIP3 of 32 dBm, and an input return loss of 15 dB. Power dissipation is rated at 339 mW. It is housed in a 16-lead QFN (3x3 mm) package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes GaAs InGaP Heterojunction Bipolar Transistor (HBT) technology for high-performance amplification.
• Provides wideband operation covering DC to 6 GHz frequencies.
• Features low power consumption suitable for portable and battery-operated systems.
• Integrated design eliminates external matching components for simplified circuit implementation.

Applications

• General purpose RF signal chain amplification
• GPS receiver front-end stages
• Wireless communication infrastructure modules
• Test and measurement equipment

Procurement Notes

Verify component status carefully as the HMC311LP3E is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized distributors or check for alternative packaging options such as cut tape versus reel if stock remains. Ensure that any substitute components meet identical electrical specifications and pin compatibility requirements before integration into existing designs to maintain system performance integrity.

Selection Notes

Select this component when a wideband, low-noise gain block is required for frequencies up to 6 GHz. The 14.5 dB gain and 4.5 dB noise figure make it suitable for sensitive receiver applications. Consider the 16-QFN package for compact PCB layouts. Evaluate thermal management needs given the 339 mW power dissipation rating. Verify that the 5 V supply voltage aligns with the system's power architecture and that the operating temperature range meets environmental constraints.
