HMC457QS16G

Overview

The HMC457QS16G is a high dynamic range GaAs InGaP Heterojunction Bipolar Transistor (HBT) monolithic microwave integrated circuit (MMIC) power amplifier. It operates within the frequency range of 1.7 to 2.2 GHz and delivers an output power of 1 watt. The device is designed for applications requiring robust performance in RF signal chains.

Feature Summary

• Utilizes GaAs InGaP HBT technology for high reliability
• Provides 1-watt output power capability
• Engineered for high dynamic range performance

Applications

• Wireless infrastructure equipment
• Point-to-point radio links
• Broadband communication systems

Procurement Notes

Verify current manufacturing status as some sources indicate this product may be obsolete or discontinued. Confirm availability through authorized Analog Devices distributors or check for valid replacement part numbers if the specific QS16G package is no longer produced. Ensure compatibility with existing board designs before procurement.

Selection Notes

Select this component when a 1-watt output power is required in the 1.7–2.2 GHz band. Consider the GaAs InGaP HBT technology for its balance of linearity and efficiency. Verify that the QSOP-16 package fits the thermal and spatial constraints of the target application compared to alternative MMIC packages.

Part Context

This part belongs to the HMC series of RF amplifiers from Analog Devices. It serves as a discrete power amplification stage, distinct from evaluation boards like the EVAL-HMC380QS16G or phase detectors such as the HMC439. It is categorized under general-purpose RF amplifiers rather than digital converters or development tools.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Analog Devices directly for obsolescence management or equivalent replacements if this specific model is discontinued.
