FMAM4043

Overview

The FMAM4043 is a medium power broadband amplifier manufactured by Fairview Microwave, designed for operation within the 2 GHz to 6 GHz frequency range. This component delivers a gain of 44 dB and achieves a saturated output power of 3 Watts. It features a P1dB compression point of 35 dBm, ensuring linear performance at high signal levels. The amplifier utilizes SMA connectors for interfacing and requires a DC supply voltage between 11 V and 15 V. It is packaged in a bag format.

Feature Summary

• Broadband amplification capability across the 2 GHz to 6 GHz spectrum
• High linearity with a P1dB point of 35 dBm
• Integrated heatsink design for thermal management
• SMA connector interface for standard RF integration

Applications

• Test and measurement instrumentation systems
• Wireless communication infrastructure
• Military and aerospace radar subsystems
• Broadband signal generation applications

Procurement Notes

Verify that the specific order includes the integrated heatsink, as this physical attribute is critical for thermal dissipation during operation. Confirm the required DC supply voltage range aligns with system power capabilities before integration. Ensure SMA connector compatibility with existing board layouts or cable assemblies to prevent impedance mismatches.

Selection Notes

Select the FMAM4043 when a fixed 44 dB gain is required across a wide bandwidth from 2 GHz to 6 GHz. Consider its 3 Watt output power capability for driving subsequent stages without additional amplification. Evaluate the thermal requirements carefully due to the medium power classification, ensuring adequate airflow or mounting surfaces are available for the included heatsink.

Part Context

This amplifier belongs to Fairview Microwave's portfolio of RF amplifiers, which also includes models like the FMAM4053F operating at lower frequencies. While sharing similar packaging and connector types, the FMAM4043 is distinct in its higher frequency coverage and specific gain characteristics tailored for broadband microwave applications.

Replacement Considerations

The FMAM4053F serves as a related alternative but operates in the 500 MHz to 4 GHz range, offering different frequency coverage. Direct substitution requires verifying that the target application does not require signals above 4 GHz, as the FMAM4053F will not function correctly in the upper portion of the FMAM4043's band.
