HMC572LC5

Overview

The HMC572LC5 is a compact GaAs MMIC I/Q downconverter in a leadless RoHS-compliant SMT package. It operates across the 24 GHz to 28 GHz frequency band with an intermediate frequency range of 0 Hz to 3.5 GHz and an LO frequency range of 9 GHz to 15.5 GHz. The device provides a small signal conversion gain of 8 dB, a noise figure of 3.5 dB, and an input P1dB compression point of -4 dBm. It functions on a single 3.5 V supply, drawing 125 mA of current, with a power dissipation of 860 mW. The unit is housed in a 32-lead LFCSP (5x5 mm) package.

Feature Summary

• Integrated I/Q demodulation for direct conversion applications
• Compact leadless surface-mount design for space-constrained layouts
• Single-supply operation simplifying power management

Applications

• K-band and Ka-band radar systems
• Point-to-point microwave radio links
• Satellite communication terminals

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request original manufacturer datasheets and test reports to confirm specifications match the part number. Inspect packaging integrity and lot traceability documentation upon receipt. Ensure handling procedures comply with moisture sensitivity levels specified in the datasheet to prevent damage during assembly.

Selection Notes

Select this component when designing high-frequency receivers requiring integrated quadrature demodulation. The wide IF bandwidth supports baseband processing flexibility. Evaluate thermal performance due to specific power dissipation requirements. Confirm that the local oscillator drive levels align with the specified input range for optimal conversion gain and linearity.

Part Context

This device belongs to the HMC572G series of RF integrated circuits. It utilizes Gallium Arsenide (GaAs) technology to achieve high performance at millimeter-wave frequencies. The family focuses on providing complete receiver solutions in minimal footprint sizes for wireless infrastructure.

Replacement Considerations

Check for HMC572LC5TR as a reel-pack variant from the same manufacturer. Verify pinout compatibility before substituting with other K-band downconverters.
