HMC483MS8GTR

Overview

The HMC483MS8GTR is a high dynamic range passive MMIC mixer manufactured by Analog Devices Inc. It operates within a frequency range of 700 MHz to 1.5 GHz and features an integrated local oscillator (LO) amplifier. The component utilizes GaAs technology and is housed in an 8-lead Mini-MSOP surface-mount package with an exposed pad for thermal management. This design supports general-purpose RF applications requiring compact integration.

Feature Summary

• Integrates a passive mixer with a dedicated LO amplifier for simplified circuit design
• Utilizes GaAs MMIC technology for high dynamic range performance
• Features an exposed pad in the 8-MSOP package to enhance thermal dissipation

Applications

• General purpose RF signal conversion
• Wireless communication systems operating in the 700 MHz to 1.5 GHz band
• Test and measurement equipment requiring low noise mixing

Procurement Notes

Verify component authenticity through authorized channels as this part is listed as obsolete. Confirm that the specific suffix matches the required package variant, as minor differences may exist between production runs or regional variants. Ensure compatibility with existing thermal management solutions due to the exposed pad requirement on the 8-MSOP footprint.

Selection Notes

Select this component when a combined mixer and LO amplifier solution is required to reduce board space. Consider the 700 MHz to 1.5 GHz operational range against system requirements. Evaluate the need for GaAs technology benefits over silicon alternatives for specific linearity needs. Verify that the surface-mount form factor aligns with assembly capabilities.

Part Context

This device belongs to the HMC series of RF mixers from Analog Devices, designed for broadband applications. It represents a class of integrated circuits that combine multiple RF functions into a single small-footprint package. The inclusion of an LO amplifier distinguishes it from basic passive mixers, offering improved drive requirements for downstream stages.

Replacement Considerations

The datasheet indicates the HMC483MS8GE as a related variant. Verify pinout and electrical specifications before substitution. No other direct public substitutes are confirmed.
