• Capable of operation as an image reject mixer or single-sideband upconverter
• Housed in a miniature hermetic module for enhanced environmental protection

RF Mixers Applications

• Very Small Aperture Terminal (VSAT) systems
• Image reject receiver architectures
• Single-sideband upconversion stages

RF Mixers Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet prior to integration. Confirm that the hermetic sealing requirements align with the target assembly process. Ensure that the 8.5 GHz to 13.5 GHz operational bandwidth meets the system's spectral needs. Check for any end-of-life notifications or obsolescence warnings from Analog Devices Inc. before finalizing the design-in decision.

RF Mixers Selection Notes

Select this module when compact size and high isolation are critical for I/Q modulation tasks. The integrated 90-degree hybrid simplifies circuit layout compared to discrete implementations. Consider the hermetic packaging if the operating environment requires robust protection against moisture or contaminants. Evaluate the passive nature of the mixer regarding conversion loss versus active alternatives.
