HMC463LP5TR

Overview

The HMC463LP5TR is a broadband GaAs PHEMT low-noise amplifier from Analog Devices (Hittite), designed for surface-mount applications. It operates within a frequency range of 2 GHz to 20 GHz and features an integrated Automatic Gain Control (AGC) circuit. The device utilizes a QFN-32 package and employs Silicon technology in its construction. This self-biasing MMIC provides stable amplification with a gain of approximately 13 dB and a noise figure between 2.5 dB and 3.5 dB at the 1 dB gain compression point, making it suitable for high-frequency signal processing tasks.

Feature Summary

• Integrates Automatic Gain Control (AGC) functionality for dynamic signal level management
• Utilizes GaAs PHEMT technology for broadband performance across 2 GHz to 20 GHz
• Features a leadless QFN-32 surface-mount package for compact PCB integration

Applications

• VSAT communication systems
• Point-to-point microwave links
• Electronic warfare receivers
• Test and measurement equipment

Procurement Notes

Verify the specific manufacturer designation, as sources list both Hittite and Analog Devices Inc. Confirm the RoHS compliance status, as documentation indicates conflicting information regarding lead-free certification. Ensure the QFN-32 package variant matches the required thermal and mechanical specifications for the target application before finalizing procurement orders.

Selection Notes

Select this component when a wide bandwidth covering 2 GHz to 20 GHz is required alongside automatic gain control capabilities. The QFN-32 package offers a compact footprint suitable for space-constrained designs. Consider the self-biasing architecture for simplified power supply requirements compared to externally biased alternatives.

Part Context

This part belongs to the HMC463G series of broadband amplifiers. It shares architectural similarities with other models in the family, such as the HMC462LP5 and HMC464LP5, but distinguishes itself through the inclusion of AGC circuitry. The TR suffix indicates that the device is supplied in a reel format for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include the HMC462LP5TR and HMC464LP5TR, which share similar packaging and frequency ranges. Verify if the AGC feature is critical; if not, standard LNA variants may suffice. Cross-reference pinouts and thermal characteristics to ensure compatibility during replacement.
