AMC-143-SMA

Overview

The AMC-143-SMA is a coupler feedback RF amplifier manufactured by MACOM Technology Solutions. It operates within a frequency range of 5 MHz to 500 MHz and utilizes Silicon (Si) technology. The device provides a typical gain of 15.8 dB with a noise figure of 2.5 dB. It delivers an output power of 6 dBm (0.004 W). This component is designed for applications requiring low bias current and high intercept points, such as GPS systems.

Feature Summary

• Coupler feedback architecture for stable amplification
• Low noise figure performance
• High intercept points
• Optimized for low bias current operation

Applications

• GPS systems
• General purpose RF amplification
• Wireless & RF integrated circuits

Procurement Notes

Verify the specific ordering suffix and package configuration directly with MACOM or authorized distributors before procurement. Confirm RoHS compliance status and lead times through official channels, as availability may vary. Ensure the selected variant matches the required SMA connector interface and frequency specifications for your design.

Selection Notes

Select this component when a wideband amplifier covering 5 MHz to 500 MHz is required. Consider its 15.8 dB gain and 2.5 dB noise figure for signal integrity. Evaluate the 6 dBm output power against system load requirements. The coupler feedback design offers advantages in linearity and stability compared to standard topologies.

Part Context

This part belongs to MACOM's RF Amplifier product category under Wireless & RF Integrated Circuits. It is distinct from other MACOM models like the AMC-145-SMA, which is characterized as a high-output amplifier. The AMC-143-SMA specifically targets general-purpose and GPS applications within its defined frequency band.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult MACOM technical support for direct replacements or cross-references based on specific electrical parameter tolerances.
