HMC666LP4ETR

RF Mixers Overview

The HMC666LP4ETR is a surface-mount BiCMOS MMIC up/down conversion mixer manufactured by Analog Devices (Hittite). It operates within the 3.1 GHz to 3.9 GHz frequency range and features an integrated local oscillator amplifier. The device utilizes SMT packaging in a 24-pin QFN configuration with an exposed pad, designed for efficient integration into high-frequency RF systems requiring compact form factors.

RF Mixers Feature Summary

• Integrates a dedicated LO amplifier directly onto the mixer die
• Supports both up-conversion and down-conversion signal processing
• Utilizes BiCMOS technology for optimized RF performance

RF Mixers Applications

• Wireless communication base stations
• Point-to-point microwave radio links
• Satellite communication ground terminals

RF Mixers Procurement Notes

Verify the specific manufacturer part number against official Analog Devices documentation to confirm the exact suffix and package variant. Ensure compatibility with the intended PCB footprint and thermal requirements before finalizing procurement orders.

RF Mixers Selection Notes

Select this component when a compact solution is required for the 3.1-3.9 GHz band with integrated LO drive capabilities. Consider the 24-pin QFN package constraints and ensure the design supports the necessary biasing conditions for the internal amplifier stages.

RF Mixers Part Context

This model belongs to the Hittite family of RF mixers, representing a transition from discrete components to highly integrated monolithic solutions. It serves as a specialized building block for modern wireless infrastructure, replacing larger traditional mixer assemblies with a single-chip alternative.

RF Mixers Replacement Considerations

Consult official Analog Devices documentation for direct cross-reference models or updated series replacements. Verify pinout compatibility and electrical specifications if substituting with other mixers in the same frequency range.
