10%帶寬兆瓦級(jí)速調(diào)管放大器
A TEN PERCENT BANDWIDTH HIGH-POWER PULSED KLYSTRON AMPLIFIER

摘要: 正 長(zhǎng)期以來(lái),人們對(duì)雷達(dá)發(fā)射機(jī)用的兆瓦級(jí)末級(jí)發(fā)射管的效率-帶寬特性和增益-帶寬特性一直很感興趣。而且雷達(dá)對(duì)發(fā)射管相位-頻率線(xiàn)性,增益平坦性和功率幅值平坦性的要求也越來(lái)越高。但是目前微波管產(chǎn)品中,尚沒(méi)有在這樣的功率電平下帶寬寬于10％的管子。由于速調(diào)管在大功率、高增益、高效率等方面與其他微波管相比,仍占有較大的優(yōu)勢(shì),因此,近十幾年來(lái),國(guó)際上許多微波管公司,廠家在展寬速調(diào)管帶寬方面仍進(jìn)行著不少具有實(shí)際意義的研究工作

關(guān)鍵詞:
Abstract: This paper describes a pulsed klystron amptifier tube with 1-2 MW peak out-put power is described. It operates at the low end of S-band. The 1 dB bandwidth is greater than 10% f0 with 40 dB gain. The tube has an overlapping mode extended interaction output section and a six cavity buncher section. It is very stable in operation. It has nearly constant gain accross the entire band. -
