引言随着捷变频技术的发展,对捷变频管频率捷变速度的要求越来越高。机械调谐速度慢,只能实现脉间变频,而电调管的调频速度可以大大提高,可实现脉内变频。本文介绍了在普通磁控管上附加一个PIN管调谐器来实现频率捷变的技术。在上灯及长风机器厂的协作下,制成了腔外PIN管电调频率捷变磁控管(401管),捷变带宽40～50兆赫、>10千瓦、跳频时间<30微秒,并进行了装机实验。测试结果表明,在捷变状态下工作稳定、频谱良好。这种管子与机调捷变频磁控管相比,没有
Introduction With the development of agile frequency technology, the agile frequency requirements of agile frequency tube are getting higher and higher. Mechanical tuning speed is slow, can only be achieved between the pulse frequency, and the ESC FM speed can be greatly improved, can be achieved within the pulse frequency. This article describes the technique of adding a PIN tube tuner to a common magnetron to achieve frequency agility. In collaboration with Shanghang and Changfeng Machinery Works, an external PIN tube ESC frequency agile magnetron (401 tubes) was manufactured. The agile bandwidth was 40-50 MHz,> 10 kW and the frequency hopping time was <30 Seconds, and conducted a test machine. The test results show that the working condition is stable and the spectrum is good under the condition of agility. This tube and machine compared to frequency modulation magnetron, no
