HMC333TR

RF Mixers Overview

The HMC333TR is a GaAs MMIC mixer with an integrated local oscillator amplifier, designed for bidirectional operation in upconversion and downconversion applications. It operates within a frequency range of 3.0 GHz to 3.8 GHz. The device features a maximum conversion loss of 11 dB and a noise figure of 11 dB. It requires a single 3 V power supply and draws 7 mA of operating current. The component is housed in a surface-mount SOT-23-6 package and supports an operating temperature range from -40°C to +85°C.

RF Mixers Feature Summary

• Integrates a balanced image-reject mixer with a dedicated LO amplifier on a single GaAs MMIC die
• Supports bidirectional signal processing for both upconversion and downconversion tasks
• Provides high isolation characteristics suitable for wireless LAN and wideband local loop systems

RF Mixers Applications

• Wireless Local Loop (WLL) systems
• Wireless Local Area Network (WLAN) infrastructure
• Upconversion stages in RF transmitters
• Downconversion stages in RF receivers

RF Mixers Procurement Notes

Verify the specific ordering suffix, as the base part number HMC333 may correspond to various tape-and-reel or cut-tape configurations. Confirm that the requested variant matches the required packaging format for your assembly line. Check current availability status, as this component has been subject to end-of-life notifications by the manufacturer. Ensure compatibility with standard SMD/SMT reflow processes given the SOT-23-6 footprint.

RF Mixers Selection Notes

Select this component when a compact solution for the 3 GHz to 3.8 GHz band is required without external LO amplification. Consider the 11 dB conversion loss and 11 dB noise figure against system link budget requirements. Evaluate the 7 mA current draw for low-power portable designs. Compare performance metrics against other mixers in the Analog Devices portfolio if wider bandwidth or lower noise is necessary.
