Ampleon Releases 3rd Generation GaN-on-SiC Transistors with Enhanced Performance

Wide frequency coverage with high efficiency and high linearity

Nijmegen, the Netherlands – Ampleon today announced two new broadband GaN-on-SiC high electron mobility transistors (HEMTs), the 30 W CLF3H0060(S)-30 and 100 W CLF3H0035(S)-100 power classes. These high linearity devices are the first products from our recently qualified and production-ready Gen 3 GaN-SiC HEMT process.

These devices offer broadband high linearity characteristics at low bias, resulting in improved broadband linearity levels (less than -32dBc for third-order intermodulation at 5dB; less than -42dBc when backed off 8dB from saturation power over a 2:1 bandwidth). Broadband linearity is critical for frequency-agile radios deployed in today’s defense electronics, which are used to handle multimode communication waveforms (from FM signals all the way to high-order QAM signals) while applying adversarial channels. These demanding applications require the transistors themselves to have better broadband linearity. Based on market feedback, Ampleon’s 3rd generation GaN-on-SiC HEMT transistors meet these extended broadband linearity requirements.

In addition, both Gen3 transistors feature thermally enhanced packaging for reliable operation and extremely rugged VSWR withstand capability of up to 15:1 for 30W devices. This ruggedness also extends to Class A amplifier operation. This is common in instrumentation applications with saturated gate conditions while maintaining linearity over a wide dynamic range over an extended frequency range. Ampleon’s Gen3 GaN-on-SiC HEMT transistors set a new standard for high linearity GaN technology for broadband applications while maintaining excellent thermal performance and ruggedness.
