FMAM5101

Overview

The FMAM5101 is a temperature-compensated low noise amplifier manufactured by Fairview Microwave. It operates within a frequency range of 0.5 GHz to 4 GHz and utilizes GaAs technology. The device provides a minimum gain of 35 dB, with typical specifications reaching 39 dB. It features a noise figure of 3 dB and a P1dB compression point of 21 dBm to 22 dBm. Operating from a supply voltage of 12 V to 15 V, it draws approximately 350 mA. The unit includes an SMA interface and heatsink for thermal management.

Feature Summary

• Temperature compensation ensures stable performance across varying environmental conditions.
• Low noise figure design optimizes signal integrity for sensitive reception applications.
• Integrated heatsink facilitates efficient thermal dissipation during operation.

Applications

• Wireless communication systems requiring low noise amplification
• Test and measurement equipment operating in the UHF to S-band ranges
• Military and aerospace radar subsystems

Procurement Notes

Verify specific gain and P1dB requirements against the official datasheet, as values may vary between the standard FMAM5101 and the temperature-compensated FMAM5101F variant. Confirm connector type and mounting style compatibility with your system design before ordering. Check current availability status as distribution may be limited or restricted in certain regions.

Selection Notes

Select this component when a broadband low noise amplifier is required between 500 MHz and 4 GHz. Consider the FMAM5101F if precise temperature stability is critical for your application. Ensure the power supply can deliver the required 350 mA at 12-15 V. Verify that the SMA interface matches your interconnect strategy.
