HMC572LC5TR

Overview

The HMC572LC5TR is a GaAs MMIC gain block from Analog Devices, designed for broadband applications. It operates within a frequency range of 10 to 40 GHz. The device provides a typical small-signal gain of 13 dB with a noise figure of 4.5 dB. Key electrical specifications include an output P1dB of +16 dBm and a third-order intercept point (IP3) of +28 dBm. It utilizes a compact LC-5 surface-mount package measuring 1.5 x 1.5 mm, facilitating integration into high-frequency RF systems requiring low power consumption and stable performance across wide bandwidths.

Feature Summary

• Broadband operation covering 10 to 40 GHz frequencies
• High linearity with +28 dBm IP3 for signal integrity
• Compact LC-5 package for space-constrained designs

Applications

• Point-to-point microwave radio links
• Satellite communication subsystems
• Test and measurement instrumentation front ends

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and lead time specifications directly from the manufacturer's current documentation. Confirm that the LC-5 package handling requirements align with your assembly capabilities. Ensure the part number corresponds exactly to the HMC572 variant to avoid functional mismatches in high-frequency circuits.

Selection Notes

Select this component when a wide bandwidth exceeding 30 GHz is required alongside moderate gain. Consider the 4.5 dB noise figure for sensitive receiver chains. Evaluate the +16 dBm output power against load mismatch conditions. Compare thermal dissipation needs against the small footprint limitations inherent to the LC-5 package size.

Part Context

This gain block belongs to the HMC5xx series of GaAs MMICs optimized for X-band through Ka-band operations. It complements other components in the family by offering higher linearity compared to lower-cost variants. The technology leverages gallium arsenide processes to achieve performance unattainable with silicon-based solutions at these frequencies.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-reference with HMC571 or HMC573 only if frequency ranges and pinouts are verified identical in official datasheets.
