HMC311LP3TR

Overview

The HMC311LP3TR is an InGaP HBT gain block MMIC amplifier manufactured by Analog Devices Inc. It operates from DC to 6 GHz and provides a typical gain of 14.5 dB with a noise figure of 4.5 dB. The device features a P1dB compression point of 15.5 dBm and an OIP3 of 32 dBm. It requires a 5 V supply current of 55 mA and dissipates 339 mW. Packaged in a QFN-16 SMD/SMT footprint, it supports input return loss of 15 dB and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes InGaP HBT technology for high-performance microwave amplification
• Provides cascadable 50 Ohm gain stage functionality
• Capable of driving LO inputs of mixers with high output power

Applications

• Cascadable RF gain stages
• Local oscillator (LO) drive for mixers
• Microwave radio systems

Procurement Notes

Verify component authenticity through authorized channels as the lifecycle status is listed as obsolete. Confirm package integrity and pin alignment against the QFN-16 specification. Ensure thermal management aligns with the 339 mW dissipation rating. Check for RoHS compliance documentation prior to integration. Validate that the DC-6 GHz frequency range meets system requirements.

Selection Notes

Select this component for applications requiring wideband DC-to-6 GHz amplification with moderate gain. Consider the 4.5 dB noise figure for low-noise front-end designs. Evaluate the 15.5 dBm P1dB limit for linearity requirements. The 5 V supply voltage must be compatible with the system power architecture. Assess the QFN-16 package size for PCB layout constraints.
