HMC333E

RF Mixers Overview

The HMC333E is a single-balanced RF mixer IC manufactured by Analog Devices Inc. using GaAs MMIC technology. It operates within the 3.0 GHz to 3.8 GHz frequency range and features an integrated local oscillator (LO) amplifier, allowing it to function as either an upconverter or downconverter. The device is housed in a surface-mount SOT-23-6 package. Key electrical parameters include a maximum conversion loss of 11 dB and a noise figure of 11 dB. It requires a 3 V supply voltage with a typical operating current of 7 mA. The component supports an industrial temperature range from -40°C to +85°C and has a power dissipation rating of 238 mW.

RF Mixers Feature Summary

• Integrates a single-balanced mixer topology with a dedicated LO amplifier for simplified circuit design
• Capable of bidirectional signal conversion, functioning effectively as both an upconverter and a downconverter
• Utilizes robust GaAs MMIC technology to ensure reliable performance in high-frequency wireless applications

RF Mixers Applications

• Wireless Local Loop (WLL) systems
• Wireless LAN (WLAN) infrastructure
• Upconversion and downconversion stages in radio frequency signal chains

RF Mixers Procurement Notes

The HMC333E is officially listed as obsolete by Analog Devices Inc., with end-of-life notifications dating back to March 2016. Procurement is restricted to remaining stock from authorized distributors or secondary market suppliers. Verify authenticity carefully due to the component's discontinued status. Ensure that any available units are genuine Analog Devices products, as counterfeits may exist for obsolete RF components. Check specific lot dates and storage conditions before integration into new designs.

RF Mixers Selection Notes

Select the HMC333E only for legacy system maintenance or repair where original specifications must be preserved. Due to its obsolete status, this component is unsuitable for new product development. Engineers should evaluate modern replacement mixers with comparable frequency ranges and lower noise figures if redesigning the circuit. Consider the availability of alternative packages and the potential need for schematic modifications when substituting this part with newer generations of RF mixers.

RF Mixers Part Context

The HMC333E belongs to the HMC333 series of RF mixers produced by Analog Devices Inc. It is part of a family of GaAs MMIC components designed for wireless communication applications. The 'E' suffix typically denotes an enhanced or specific variant within the series, often related to packaging or testing standards. This component sits within the broader category of Wireless & RF Integrated Circuits, specifically targeting sub-categories like mixers and converters for frequencies above 3 GHz.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. As the HMC333E is obsolete, engineers must consult Analog Devices technical support or distributor catalogs for current equivalents. No direct cross-reference part numbers are verified in the text.
