HMC333

RF Mixers Overview

The HMC333 is a GaAs MMIC single-balanced mixer with an integrated local oscillator amplifier, operating between 3.0 and 3.8 GHz. It functions as an upconverter or downconverter in SOT-23-6 packages. Key electrical parameters include a maximum conversion loss of 11 dB and a noise figure of 11 dB. The device operates on a 3 V supply with a current draw of 7 mA, dissipating 238 mW. It supports surface-mount installation across a temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• Integrates a single-balanced mixer topology with a dedicated LO amplifier for simplified circuit design.
• Supports bidirectional frequency conversion capabilities for both upconversion and downconversion applications.
• Utilizes Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit technology for high-frequency performance.

RF Mixers Applications

• Wireless Local Loop (WLL) systems
• Wireless Local Area Network (WLAN) infrastructure
• General RF signal chain conversion stages

RF Mixers Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance requirements against specific project standards, as historical data indicates non-compliance for certain variants. Validate package integrity upon receipt to ensure suitability for automated surface-mount assembly processes.

RF Mixers Selection Notes

Evaluate the 11 dB conversion loss and 11 dB noise figure against system link budget requirements. Ensure the 3.0–3.8 GHz operational band aligns with target frequency specifications. Consider the SOT-23-6 footprint constraints and thermal dissipation limits of 238 mW for PCB layout planning.
