• Features excellent gain flatness from 6 GHz to 18 GHz to maintain signal integrity.
• Includes internal DC blocking and 50 Ohm impedance matching for direct system integration.
• Operates on a single +5 V supply with self-biasing design to simplify circuit requirements.

Applications

• Telecommunications infrastructure
• Microwave radio links
• Very Small Aperture Terminal (VSAT) systems
• Military electronic warfare and command, control, communications, and intelligence (C3I) systems
• Test instrumentation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and specific packaging variants such as cut tape or reel options prior to ordering. Ensure that the selected part number matches the required operational frequency range and thermal specifications for the intended application environment.

Selection Notes

Select this component for applications requiring wideband amplification from 2 GHz to 20 GHz with minimal signal degradation. The low noise figure and high linearity make it suitable for sensitive receiver front-ends. Consider the QFN-32 package dimensions for PCB layout constraints and ensure adequate thermal management due to the specified power dissipation levels during operation.
