HMC460-SX

Overview

The HMC460-SX is a GaAs MMIC PHEMT Low Noise Distributed Amplifier die manufactured by Analog Devices Inc. It operates across a frequency range of 0Hz to 20GHz. Key electrical parameters include a typical gain of 14dB, a noise figure of 2.5dB, and a 1dB compression point (P1dB) of 16dBm. The device features an input return loss of 22dB and has a power dissipation rating of 2.17W. It is designed for surface mount installation in a die package format.

Feature Summary

• Utilizes GaAs PHEMT technology for low noise performance
• Distributed amplifier architecture enables wideband operation from DC to 20GHz
• High linearity with 16dBm P1dB output power
• Optimized for high-gain applications requiring low insertion loss

Applications

• Wideband RF signal chain integration
• Test and measurement instrumentation front-ends
• Military and aerospace radar systems
• Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix 'SX' indicates the bare die configuration rather than packaged variants. Confirm RoHS3 compliance status through official documentation prior to integration. Ensure handling procedures account for the sensitive nature of the exposed die substrate. Cross-reference the datasheet revision date to validate parameter accuracy against current manufacturing standards.

Selection Notes

Select this component when a wide bandwidth extending to 20GHz is required alongside low noise characteristics. The distributed topology supports flat gain over a broad spectrum compared to narrowband designs. Consider the 2.17W power dissipation requirement for thermal management in the final assembly. Evaluate the 14dB gain level against system noise budget requirements.

Part Context

This part belongs to the HMC460 family of low noise amplifiers. The '-SX' suffix typically denotes the silicon die form factor intended for custom packaging or hybrid integration. It complements other Analog Devices RF solutions like the HMC465 series for broader frequency coverage needs.
