HMC994APM5E

Overview

The HMC994APM5E is a GaAs pHEMT MMIC distributed broadband power amplifier operating from DC to 28 GHz. It delivers 13 dB gain, +27 dBm P1dB output power, and +29 dBm saturated output power with 23% PAE at +10V supply. The device features an input IP3 of +38 dBm and internal 50-ohm matching. Packaged in a 32-pin 5x5 mm LFCSP, it supports -40°C to +85°C operation.

Feature Summary

• Integrated 50-ohm input and output matching for direct system integration
• High linearity performance suitable for demanding RF applications
• Broadband frequency coverage extending from DC to 28 GHz

Applications

• Electronic Warfare (EW) systems
• Electronic Countermeasures (ECM)
• Radar test equipment
• Military and space communications

Procurement Notes

Verify the specific suffix 'E' against the datasheet to confirm lead-free status and tape/reel specifications. Ensure the ordering part number matches the exact package variant required for the PCB footprint. Confirm RoHS compliance documentation is available from the manufacturer before finalizing procurement.

Selection Notes

Select this component when wide bandwidth up to 28 GHz is required alongside high linearity. The integrated 50-ohm matching simplifies circuit design compared to unmatched variants. Consider thermal management due to power dissipation requirements in the 5x5 mm package for sustained high-power operations.

Part Context

This part belongs to the HMC994 series of GaAs pHEMT MMICs. It serves as a high-performance solution for ultra-wideband signal amplification. The device is designed to replace discrete transistor solutions, offering superior gain flatness and reduced board space in critical RF front-end architectures.
