FMAM5105

Overview

The FMAM5105 is a temperature-compensated low noise amplifier manufactured by Fairview Microwave, utilizing GaAs technology. It operates within a frequency range of 4 GHz to 12 GHz and requires a supply voltage between 12 V and 15 V with a current draw of 350 mA. The device provides a typical gain of 39 dB and a minimum gain of 35 dB, with a noise figure of 4 dB. Key performance metrics include a 1 dB compression point (P1dB) of 22 dBm. It features SMA connectors and is designed for surface mount installation, functioning reliably within an operating temperature range of -55°C to +85°C.

Feature Summary

• Temperature compensated design ensures stable performance across varying thermal conditions
• High linearity output with 22 dBm P1dB compression point
• Broadband operation covering 4 GHz to 12 GHz spectrum
• Low noise figure specification for sensitive signal reception

Applications

• Point-to-point microwave radio links
• Satellite communication ground stations
• Test and measurement instrumentation front-ends

Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure compatibility with required gain and connector specifications. Confirm that the SMA interface matches system requirements. Check for updated environmental compliance certifications if deploying in regulated regions. Ensure proper ESD handling procedures are followed during installation due to the sensitive GaAs internal components.

Selection Notes

Select this component when broadband amplification between 4 GHz and 12 GHz is required with minimal signal degradation. The temperature compensation feature makes it suitable for outdoor or uncontrolled environments where thermal stability is critical. Compare noise figure and gain flatness against alternative models if strict sensitivity thresholds exist. Verify power supply constraints align with the 12 V to 15 V operational range before integration.
