HMC570-SX

Overview

The HMC570-SX is a Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit (MMIC) functioning as an I/Q receiver die. It operates within the 17 to 21 GHz frequency range, utilizing a local oscillator frequency of 12 GHz and producing a 3.5 GHz intermediate frequency output. The component provides a gain of 12 dB with a noise figure of 4 dB. It requires a 3.5 V supply voltage and draws 125 mA of current. Key performance metrics include a P1dB compression point of -4 dBm and a power dissipation of 920 mW. The device supports an operating temperature range from -55°C to +85°C.

Feature Summary

• Integrates dual-channel I/Q downconversion architecture for precise signal demodulation
• Utilizes GaAs MMIC technology to achieve high-frequency operation in a bare die format
• Provides fixed intermediate frequency output to simplify downstream baseband processing

Applications

• Radar systems requiring direct RF-to-baseband conversion
• Satellite communication ground stations
• Point-to-point microwave radio links

Procurement Notes

Verify that the procurement channel supplies the specific 'SX' suffix variant, which denotes the bare die configuration. Confirm compatibility with surface-mount assembly processes suitable for unencapsulated semiconductor dies. Ensure handling protocols account for the sensitivity of exposed GaAs substrates during installation. Cross-reference the manufacturer's latest datasheet to validate current availability status, as supply conditions may vary.

Selection Notes

Select this component when a compact, high-performance I/Q receiver is required for frequencies between 17 and 21 GHz. The fixed 3.5 GHz IF output dictates system architecture constraints. Evaluate thermal management capabilities due to the 920 mW power dissipation in a die package. Consider the 125 mA current draw against available power budgets. This part is suitable for applications prioritizing size reduction over packaged convenience.

Part Context

The HMC570 belongs to Analog Devices' family of RF mixer MMICs designed for high-frequency wireless applications. The '-SX' suffix specifically identifies the bare die version of the HMC570G series, intended for custom substrate integration. It serves as a critical active element in up/downconverter chains, bridging the gap between RF front-ends and digital signal processors in advanced communication hardware.
