HMC463LP5

Overview

The HMC463LP5 is a GaAs PHEMT MMIC Low Noise AGC Amplifier from Analog Devices, operating within the 2 GHz to 20 GHz frequency range. Packaged in a leadless 5x5 mm QFN-32 surface mount device, it features an integrated Automatic Gain Control (AGC) circuit. Key electrical specifications include a typical gain of 13 dB and a noise figure of 3 dB. The amplifier operates on a single 5 V supply with a current consumption of 60 mA. It delivers a P1dB compression point of 19 dBm and an OIP3 of 30 dBm. The input return loss is specified at 15 dB, with a power dissipation of 1.24 W. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates Automatic Gain Control (AGC) functionality for dynamic signal management
• Utilizes GaAs PHEMT MMIC technology for high-frequency performance
• Features a compact leadless 5x5 mm QFN-32 surface mount package

Applications

• W-band low noise amplification systems
• Satellite communication receivers
• Electronic warfare applications requiring wideband gain control

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special orders. Confirm that the specific LP5 suffix matches the required leadless QFN-32 package variant. Ensure compatibility with the 5 V single-supply requirement and check for any RoHS compliance documentation updates prior to final procurement decisions.

Selection Notes

Select this component when wideband operation from 2 GHz to 20 GHz is required alongside automatic gain control capabilities. The 13 dB gain and 3 dB noise figure make it suitable for sensitive receiver front-ends. Consider the 60 mA current draw and 1.24 W power dissipation for thermal management design. The QFN-32 package requires appropriate PCB layout techniques for thermal relief and RF grounding.

Part Context

The HMC463LP5 belongs to the HMC463G series of low noise amplifiers. It is part of Analog Devices' portfolio of GaAs MMICs designed for high-performance RF applications. The LP5 designation indicates the specific leadless QFN-32 packaging option, distinguishing it from other package variants within the same functional family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if the HMC462LP5 offers compatible performance characteristics, though specific parameter matching is required.
