FMAM5082

Overview

The FMAM5082 is a GaN power amplifier from Fairview Microwave, operating from 1 GHz to 2.5 GHz. It delivers 18W Psat with 47 dB gain and 50% efficiency in Class A mode. The unit requires an operating supply voltage of 11 V to 32 V and draws 1.9 A current. It features SMA connectors and includes an integrated heatsink with a cooling fan for thermal management.

Feature Summary

• Utilizes Gallium Nitride (GaN) technology for high-power performance
• Integrates active cooling via a built-in fan and heatsink assembly
• Operates in linear Class A mode for signal fidelity

Applications

• L-band radar systems
• S-band communication links
• Broadband test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and mechanical dimensions before integration. Confirm that the external power supply meets the 11 V to 32 V range and 1.9 A current requirement. Ensure adequate airflow is maintained for the integrated fan to prevent thermal shutdown during continuous operation.

Selection Notes

Select this component when high output power and linearity are required in the L and S bands. The integrated cooling solution simplifies enclosure design by removing the need for external heat sinks. Verify SMA connector compatibility with existing RF interconnects.

Part Context

This model belongs to the Fairview Microwave RF amplifier portfolio, which provides pre-matched, broadband solutions for wireless infrastructure. The FMAM series typically integrates matching networks and bias circuits into compact modules, reducing design complexity for engineers developing high-frequency transmission systems.
