HMC1022ACHIPS

Overview

The HMC1022ACHIPS is a GaAs pHEMT MMIC distributed power amplifier operating from DC to 48 GHz. It delivers 11.5 dB small signal gain and 0.25 W (25 dBm) output power at 1 dB gain compression. The device features a typical output third-order intercept point of 33 dBm and an input return loss of 17 dB. Powered by +10 V at 150 mA, it includes internal 50 Ω matching for easy integration. Operating temperatures range from -55°C to +85°C.

Feature Summary

• Distributed architecture provides stable gain and power performance across a wide frequency range up to 48 GHz.
• Internal 50 Ω input and output matching simplifies integration into multi-chip modules without external matching networks.
• High linearity characteristics with significant output third-order intercept point support complex modulation schemes.
• Robust thermal and electrical specifications allow operation in demanding environments including military and aerospace applications.

Applications

• Electronic Warfare systems
• Electronic Countermeasures equipment
• Radar transceivers
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'CHIPS' against the manufacturer's official datasheet to confirm the die package type and handling requirements. Ensure ESD protection protocols are strictly followed during assembly due to the bare die format. Cross-reference the current lifecycle status with Analog Devices directly, as distribution channels may list varying availability or obsolescence statuses that do not reflect factory production reality.

Selection Notes

Select this component when designing systems requiring broadband amplification from DC through millimeter-wave frequencies. The internal 50 Ω matching eliminates the need for external RF components, reducing board space and complexity. Consider the +10 V supply requirement and 150 mA current draw for power budgeting. Verify that the thermal dissipation capabilities meet the system's heat management constraints for the intended operating temperature range.
