HMC341-SX

Overview

The HMC341-SX is a GaAs MMIC Low Noise Amplifier (LNA) manufactured by Analog Devices Inc. It operates within the frequency range of 21GHz to 29GHz, with specific testing conducted between 24GHz and 26GHz. The device provides a gain of 13dB and maintains a noise figure of 3dB. Key performance metrics include a P1dB of 8.5dBm. Electrical requirements consist of a supply voltage of 3V and a supply current of 35mA. The component is supplied in a die package format for surface mount integration.

Feature Summary

• Utilizes GaAs MMIC technology for low noise amplification
• Designed for wideband operation across Ka-band frequencies
• Optimized for easy integration into multi-chip modules

Applications

• GPS receiver front-ends
• Point-to-point microwave radio links
• Satellite communication systems

Procurement Notes

Verify that the procurement channel sources genuine Analog Devices Inc. components. Confirm the part number suffix matches the die configuration. Ensure compliance with RoHS3 specifications and check MSL ratings for handling during assembly. Cross-reference datasheet revisions to confirm electrical parameter consistency before finalizing orders.

Selection Notes

Select this component when a high-gain, low-noise solution is required for frequencies up to 29GHz. The die package requires careful PCB layout and bonding considerations compared to standard surface-mount packages. Evaluate thermal management needs due to the 35mA supply current. Consider the 3V supply requirement against system power constraints.

Part Context

This part belongs to the HMC341 family of RF amplifiers. The -SX suffix typically denotes a specific packaging or processing variant, often referring to the bare die form factor as indicated by distributor listings. It shares core electrical characteristics with other variants like the HMC341LC3BTR but differs in physical packaging and handling requirements.

Replacement Considerations

The HMC341LC3BTR offers similar electrical performance but utilizes a 12-SMT (3x3) QFN package instead of a bare die. Verify pinout compatibility and thermal dissipation differences when substituting. Ensure the application can accommodate the different mounting and assembly processes required for the alternative package type.
