HMC571

Overview

The HMC571 is a GaAs MMIC I/Q downconverter chip designed for the 21 GHz to 25 GHz frequency range. It provides a small signal conversion gain of 10 dB and achieves a noise figure of 3 dB. The device operates with a supply voltage of 3.5 V and draws a current of 125 mA. Key specifications include an LO frequency of 14 GHz, an IF frequency of 3.5 GHz, and a P1dB compression point of -6 dBm. The maximum operating temperature is +85°C.

Feature Summary

• Integrates I/Q downconversion functionality within a compact GaAs MMIC form factor
• Delivers high-frequency performance in the 21-25 GHz operational band
• Provides low noise figure characteristics suitable for sensitive receiver applications

Applications

• Radar systems requiring downconversion in the K-band
• Point-to-point microwave communication links
• Electronic warfare receivers
• Satellite communication ground stations

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions meet moisture sensitivity level requirements for die-level components. Validate electrical parameters against the official datasheet specifications during incoming inspection to guarantee performance consistency.

Selection Notes

Select the HMC571 when a compact solution is required for I/Q downconversion in the 21-25 GHz range. Consider its 3 dB noise figure and 10 dB gain for low-noise front-end designs. Evaluate the 3.5 V supply requirement and 125 mA current draw against system power constraints. Ensure the 14 GHz LO frequency aligns with available local oscillator sources and that the 3.5 GHz IF matches downstream processing bandwidths.

Part Context

The HMC571 belongs to the HMC571G series of up/down converters manufactured by Analog Devices Inc. It is categorized under Wireless & RF Integrated Circuits. The component utilizes GaAs technology to achieve high-frequency operation. It is distinct from the HMC571LC5TR-R5, which is a surface-mount variant in an LFCSP-32 package, whereas the HMC571 is typically supplied as a die.
