최근에는 성능 향상을 위해 마이크로파 전력 증폭기에 GaN 장치를 채택하는 경우가 많습니다. 그리고 마이크로파 전력 증폭기의 새로운 설계 방법이 많이 제안되었습니다. 그 결과, 고효율, 초소형 마이크로파 신호 소스를 쉽게 사용할 수 있게 되었습니다. 이는 새로운 마이크로파 가열 시스템의 길을 열어줍니다. 본 논문에서는 마이크로파 전력증폭기의 설계방법과 마이크로파 가열의 응용에 대한 최근의 진행상황을 기술한다. 먼저, GaN 트랜지스터의 디바이스 모델에 대해 설명합니다. 전기적 비선형 등가 장치 모델에 등가 열 모델이 도입되었습니다. 두 번째에서는 고효율 전력 증폭기 설계를 위한 ALP(Active Load-Pull) 측정 시스템에 대해 설명합니다. 기존의 폐루프 ALP 시스템의 원리를 설명한다. 폐쇄 루프 ALP 시스템의 진동 위험을 피하기 위해 새로운 ALP 시스템이 제안되었습니다. 세 번째에서는 마이크로파 가열 시스템에 대해 설명한다. 가열 시스템은 반사파를 모니터링합니다. 그런 다음 신호 소스의 주파수와 안테나 간의 위상차를 제어하여 반사파를 최소화합니다. 주파수와 위상을 조절하여 90% 이상의 흡수효율을 얻었습니다. 마지막 부분에서는 의료기기의 응용에 대해 설명합니다.

Abstract: Recently, GaN devices are often adopted in microwave power amplifiers to improve the performances. And many new design methods of microwave power amplifier were proposed. As a result, a high-efficiency and super compact microwave signal source has become easily available. It opens up the way for new microwave heating systems. In this paper, the recent progress on design methods of microwave power amplifier and the applications for microwave heating are described. In the first, a device model of GaN transistor is explained. An equivalent thermal model is introduced into the electrical non-linear equivalent device model. In the second, an active load-pull (ALP) measurement system to design a high-efficiency power amplifier is explained. The principle of the conventional closed-loop ALP system is explained. To avoid the risk of oscillation for the closed-loop ALP system, novel ALP systems are proposed. In the third, a microwave heating system is explained. The heating system monitors the reflection wave. Then, the frequency of the signal source and the phase difference between antennas are controlled to minimize the reflection wave. Absorption efficiency of more than 90% was obtained by the control of frequency and phase. In the last part, applications for a medical instrument is described.
