5.3GHz 클라이스트론(klystron)이 최근 설계 및 제작되었습니다. 많은 국가에서 5.6GHz(5,600~5,650MHz)의 송신 주파수가 C 대역 기상 레이더에 일반적으로 사용됩니다. 그러나 일본에서는 일반적으로 5.3GHz를 사용합니다. 도플러 레이더로 낮은 수준의 윈드 시어를 감지하려면 안정적인 간섭성 마이크로파를 생성하는 MOPA(마스터 발진기 및 전력 증폭기)를 사용하는 것이 필수적입니다. 클라이스트론(klystron)이 이러한 목적에 가장 적합합니다. 그러나 5.3GHz에서 작동하는 C 대역에는 상용화된 클라이스트론이 없습니다. 우리는 원래 S-밴드와 X-밴드용으로 고안된 시뮬레이션 기술을 사용하여 이 밴드용 klystron을 개발했습니다. 클라이스트론은 5,250~5,350MHz 사이의 주파수에서 작동합니다. 일반적인 작동 매개변수는 200kW의 피크 출력 전력, 1μs의 펄스 폭, 0.002의 RF 듀티 사이클입니다. 자기장을 집중시키는 전자석을 포함한 클라이스트론은 길이가 약 67cm, 직경이 40cm, 무게는 162kg이다. 위상 변조는 이 클라이스트론이 사용되는 레이더에 의한 도플러 속도 측정의 최소 분해능에 필요한 위상 변화의 20% 미만으로 억제됩니다. 클라이스트론은 일본 주요 공항에서 운용되는 도플러 레이더에 유리한 성능을 보여준다.

Abstract: A 5.3-GHz klystron has been recently designed and fabricated. In many countries, the transmitting frequency of 5.6 GHz (5,600 to 5,650 MHz) is commonly used for C-band meteorological radars. However, 5.3 GHz is generally used in Japan. To detect low-level wind shears by a Doppler radar, it is essential to use a MOPA (Master Oscillator and Power Amplifier) that generates stable coherent microwaves. The klystron is most suitable for this purpose. However, there are no commercially available klystrons in C-band that operate at 5.3 GHz. We developed a klystron for this band, making use of a simulation technique originally devised for S- and X-bands. The klystron operates at frequencies between 5,250 and 5,350 MHz. The typical operating parameters are a peak output power of 200 kW, a pulse width of 1 µs, and an RF duty cycle of 0.002. The klystron, including the electromagnet for focusing the magnetic field, is approximately 67 cm long with a diameter of 40 cm and a weight of 162 kg. Phase modulation is suppressed below 20% of the phase change required for the minimum resolution of Doppler velocity measurement by the radar for which this klystron is employed. The klystron shows favorable performance for Doppler radars operated in major airports in Japan.
