RF Amplifiers Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and tape/reel specifications. Confirm that the required evaluation board, such as the ADPA1105-EVALZ, is available for design validation. Check for any product change notifications or manufacturing updates that may affect pinout or thermal characteristics before finalizing procurement orders.

RF Amplifiers Selection Notes

Select this component when designing systems requiring high output power in the UHF/L-band spectrum. Ensure the application circuit can support the 50 V supply requirement and manage the thermal load associated with 35W output. Consider the LFCSP-32 package dimensions for PCB layout constraints. Verify that the system bandwidth aligns with the specified 900 MHz to 1.6 GHz operational range for optimal gain flatness.

RF Amplifiers Part Context

This part belongs to the ADPA1105 series of GaN power amplifiers manufactured by Analog Devices. It is distinct from other series members like the ADPA1106, which targets higher frequencies up to 3.5 GHz. The ADPA1105ACGZN is specifically engineered for general-purpose RF applications requiring robust power handling and wide bandwidth within the lower microwave frequency bands.
