HMC351S8

RF Mixers Overview

The HMC351S8 is a double-balanced RF mixer IC manufactured by Analog Devices Inc., designed for general-purpose up/down conversion applications. It operates within a frequency range of 700 MHz to 1.2 GHz and is housed in an 8-lead plastic surface-mount SOIC package. The device utilizes a passive GaAs Schottky diode architecture with integrated planar on-chip baluns. Key electrical specifications include a maximum conversion loss of 11.5 dB and a noise figure of 11.5 dB. The component supports a maximum operating temperature of +85°C, ensuring reliable performance in standard industrial environments.

RF Mixers Procurement Notes

Verify the specific ordering suffix (S8) to ensure compatibility with required packaging formats, such as cut strip or tape and reel configurations. Confirm that the 8-SOIC package dimensions align with the target PCB footprint. Check current product status, as this component may be classified as obsolete in certain distributor catalogs, requiring validation of availability through official Analog Devices channels before finalizing procurement plans.

RF Mixers Selection Notes

Select the HMC351S8 when a passive double-balanced mixer is required for frequencies between 700 MHz and 1.2 GHz. Consider its 11.5 dB conversion loss and noise figure against system link budget requirements. The integrated on-chip baluns reduce external component count compared to discrete solutions. Ensure the application environment stays within the specified +85°C maximum operating temperature limit for optimal reliability.

RF Mixers Part Context

The HMC351S8 belongs to the HMC351 series of RF mixers from Analog Devices. It shares architectural similarities with other members of the family but is distinguished by its specific 8-lead SOIC surface-mount packaging. This configuration differentiates it from leaded or larger package variants within the same functional group, offering a compact solution for space-constrained RF designs.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if the EVAL-HMC351S8 evaluation board is suitable for prototyping needs. Consult official Analog Devices resources for potential cross-references or updated series replacements.
