GaN HEMT Devices
GaN HEMT devices use gallium nitride material and a high-electron-mobility structure to deliver RF power at higher voltage and power density than many conventional RF transistor technologies. They are used where amplifier stages need compact size, bandwidth and thermal headroom.
Typical use
Applications include broadband power amplifiers, pulsed radar transmitters, electronic-warfare hardware, satellite payload amplifiers, microwave modules and high-efficiency driver or final stages.
Engineering data
- Drain voltage, output power, gain, efficiency and breakdown behavior define the operating envelope.
- Thermal resistance, package style and flange or die attach path affect continuous and pulsed operation.
- Load-pull data, matching network needs and linearity behavior shape the surrounding amplifier design.

How to Select and Verify RF ICs, MMICs and Semiconductor Devices
Turn an RF semiconductor shortlist into an executable design decision by controlling datasheet conditions, reference planes, stability, bias and protection, package and PCB interfaces, thermal limits, fixture removal, production spread and acceptance evidence.
