HMC204

Overview

The HMC204 is a passive miniature frequency doubler implemented as a monolithic microwave integrated circuit (MMIC) die. It operates within a frequency range of 4 GHz to 8 GHz and is designed for VSAT applications. The device provides typical suppression of undesired fundamental and higher-order harmonics at 38 dB. This component serves as the bare die variant, distinct from packaged versions such as the HMC204MS8G.

Feature Summary

• Passive MMIC die architecture for frequency doubling
• High harmonic suppression performance

Applications

• VSAT systems
• RF signal chain integration
• Microwave frequency multiplication

Procurement Notes

Verify part status carefully as the HMC204 is listed as obsolete in multiple distributor records. Confirm availability of legacy stock or qualified replacement components like the HMC368LP4E. Ensure design-in compatibility with existing PCB layouts if transitioning from packaged variants.

Selection Notes

Select this component only if bare die integration is required for specific form factor constraints. Compare against packaged alternatives like the HMC204MS8G for ease of assembly. Evaluate thermal management requirements inherent to MMIC die mounting versus surface mount packages.

Part Context

The HMC204 belongs to Analog Devices' RF IC family, specifically functioning as a frequency doubler. It is often referenced alongside its packaged counterpart, the HMC204MS8G, which utilizes an 8-lead MSOP package. The die version offers flexibility for custom substrate integration in high-frequency designs.

Replacement Considerations

The HMC368LP4E is identified as a similar replacement option.
