Fraunhofer Institute for Applied Solid State Physics IAF
The IEEE Tatsuo Itoh Award 2023 of the IEEE Microwave Theory and Technology Society (MTT-S) goes to two scientists of Fraunhofer IAF: Dr. Fabian Thome and Dr. Arnulf Leuther are awarded for their paper “A 75–305-GHz Power Amplifier MMIC With 10–14.9-dBm Pout in a 35-nm InGaAs mHEMT Technology.” The IEEE Tatsuo Itoh Award is presented annually to the most significant paper in the IEEE Microwave and Wireless Component Letters. The award ceremony will take place in June at the IEEE MTT-S International Microwave Symposium 2023 in San Diego, CA.
In their paper, Fabian Thome and Arnulf Leuther present the first power amplifier monolithic microwave integrated circuit (PA-MMIC) with octave bandwidth that delivers an output power of 10 dBm at 300 GHz. The PA-MMIC represents a significant extension of the previous state of the art and impressively demonstrates the suitability of traveling wave amplifier concepts for power generation in the THz frequency range.
The authors developed the PA-MMIC using Fraunhofer IAF’s 35-nm InGaAs mHEMT technology. The PA-MMIC can be used in applications such as wireless point-to-point communication links or high-resolution radar systems and measurement devices that operate in the frequency range up to 300 GHz and rely on a wide operating bandwidth.
