HMC579

Overview

The HMC579 is an active broadband frequency multiplier die utilizing GaAs PHEMT technology. It functions as a x2 multiplier with an output frequency range of 32 GHz to 46 GHz. The device requires a +3 dBm drive signal and delivers a +13 dBm output power. Electrical operation is supported by a supply voltage between 4.5 V and 5.5 V, drawing 70 mA of current. Power dissipation is rated at 656 mW. The component operates within a temperature range of -55°C to +85°C and is supplied in a gel pack.

Feature Summary

• Active broadband multiplication using GaAs PHEMT technology
• High output power generation from low drive levels
• Wideband operational frequency coverage

Applications

• Millimeter-wave radar systems
• Point-to-point microwave communication links
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation when ordering, as the base part number may refer to the bare die while suffixes like SX indicate specific packaging or handling variations. Confirm availability status directly with Analog Devices or authorized distributors, as this component is subject to limited supply conditions. Ensure that the procurement channel provides valid traceability for the GaAs die quality and integrity prior to integration into final assemblies.

Selection Notes

Select the HMC579 when a compact solution for doubling frequencies up to 46 GHz is required. The device is suitable for designs needing high output power from minimal input drive. Consider the bare die format for custom substrate integration. Evaluate thermal management requirements given the 656 mW dissipation rating. Ensure the driving source can provide the necessary +3 dBm signal level for optimal performance.
