FMAM5104

Overview

The FMAM5104 is a temperature-compensated low noise amplifier manufactured by Fairview Microwave. It operates within the frequency range of 2 GHz to 8 GHz and utilizes GaAs technology. The device provides a minimum gain of 35 dB, with typical performance reaching 39 dB. It features a noise figure of 3.5 dB and a P1dB compression point of 22 dBm. Electrical operation requires a supply voltage between 12 V and 15 V, drawing 350 mA of current. The component includes an SMA interface and is designed for mounting with a heatsink.

Feature Summary

• Temperature compensation ensures stable gain performance across varying thermal conditions
• Low noise figure design optimizes signal integrity in sensitive RF front-ends
• Integrated heatsink facilitates thermal management for sustained high-power operation

Applications

• Wireless communication systems requiring wideband amplification
• Test and measurement equipment operating in the UHF and SHF bands
• Military and aerospace radar subsystems

Procurement Notes

Verify specific lot codes and manufacturing dates upon order confirmation, as availability may be restricted. Confirm that the required SMA connector orientation matches your system integration needs. Ensure power supply specifications strictly adhere to the 12 V to 15 V range to prevent device damage. Review the official datasheet for detailed thermal dissipation requirements associated with the integrated heatsink before finalizing procurement.

Selection Notes

Select this component when a wide bandwidth covering 2 GHz to 8 GHz is required alongside low noise characteristics. The temperature-compensated nature makes it suitable for environments with significant thermal fluctuations. Consider the 350 mA current draw and 12–15 V supply requirement during power budget planning. The inclusion of a heatsink indicates suitability for applications where passive cooling or active airflow is available to maintain optimal junction temperatures.
