同轴磁控(kong)管(guan)和机(ji)械(xie)可(ke)调脉冲同轴磁控(kong)管(guan)，采用强迫风冷，具有调谐方便，频率(lv)(lv)稳(wen)定(ding)性好，效(xiao)率(lv)(lv)高等优点，用于雷达发(fa)射机(ji)中作微(wei)波功率(lv)(lv)振荡源(yuan)。
行(xing)波(bo)管(guan)是(shi)靠连续调制电(dian)子注的速度(du)来(lai)实现放(fang)大(da)功能(neng)(neng)的微(wei)(wei)波(bo)电(dian)子管(guan)。在行(xing)波(bo)管(guan)中(zhong)，电(dian)子注同(tong)慢(man)波(bo)电(dian)路(lu)中(zhong)行(xing)进的微(wei)(wei)波(bo)场发生(sheng)相互作用(yong)，在长达6～40个波(bo)长的慢(man)波(bo)电(dian)路(lu)中(zhong)电(dian)子注连续不断(duan)地把动能(neng)(neng)交给微(wei)(wei)波(bo)信号场，从而(er)使信号得(de)(de)到(dao)放(fang)大(da)。行(xing)波(bo)管(guan)让(rang)电(dian)子穿过一(yi)个长慢(man)波(bo)结构。由于作用(yong)时间长，增(zeng)益很高，同(tong)时没有谐振腔，工作带(dai)宽大(da)大(da)增(zeng)加(jia)。行(xing)波(bo)管(guan)（TWT）的功用(yong)在于将微(wei)(wei)波(bo)讯号放(fang)大(da)。待放(fang)大(da)的微(wei)(wei)波(bo)信号经输入(ru)能(neng)(neng)量耦合器进入(ru)慢(man)波(bo)电(dian)路(lu)、并沿慢(man)波(bo)电(dian)路(lu)行(xing)进。电(dian)子与行(xing)进的微(wei)(wei)波(bo)场进行(xing)能(neng)(neng)量交换、使微(wei)(wei)波(bo)信号得(de)(de)到(dao)放(fang)大(da)。
前向(xiang)波(bo)放(fang)(fang)大(da)管主要用(yong)(yong)于行波(bo)管+前向(xiang)波(bo)放(fang)(fang)大(da)管的(de)放(fang)(fang)大(da)链发(fa)射(she)机(ji)体(ti)制(zhi)的(de)雷达中，随(sui)着国(guo)外(wai)固(gu)(gu)态+前向(xiang)波(bo)放(fang)(fang)大(da)管放(fang)(fang)大(da)链雷达的(de)成(cheng)(cheng)功应用(yong)(yong)及表现出的(de)优越(yue)性(xing)能，装(zhuang)备这种发(fa)射(she)机(ji)体(ti)制(zhi)的(de)雷达，将是未(wei)来的(de)我(wo)国(guo)地面(mian)和(he)舰载高性(xing)能雷达的(de)很好选择。S波(bo)段(duan)高增益(yi)大(da)工(gong)作比前向(xiang)波(bo)放(fang)(fang)大(da)管的(de)研(yan)(yan)制(zhi)，目的(de)就是探讨和(he)研(yan)(yan)究固(gu)(gu)态放(fang)(fang)大(da)器(qi)+前向(xiang)波(bo)放(fang)(fang)大(da)器(qi)的(de)放(fang)(fang)大(da)链在雷达发(fa)射(she)机(ji)的(de)应用(yong)(yong)，S波(bo)段(duan)高增益(yi)大(da)工(gong)作比前向(xiang)波(bo)放(fang)(fang)大(da)管研(yan)(yan)制(zhi)成(cheng)(cheng)功将推动这种体(ti)制(zhi)雷达的(de)应用(yong)(yong)成(cheng)(cheng)为现实。
管内充有气(qi)体或(huo)蒸(zheng)气(qi)的电(dian)(dian)子(zi)(zi)(zi)管，又名离子(zi)(zi)(zi)管。在(zai)充气(qi)管内,电(dian)(dian)子(zi)(zi)(zi)在(zai)电(dian)(dian)极间(jian)(jian)运动(dong)时与气(qi)体原(yuan)子(zi)(zi)(zi)和(he)分子(zi)(zi)(zi)碰撞,产(chan)生(sheng)电(dian)(dian)离现象，运动(dong)较慢(man)的正离子(zi)(zi)(zi)抵(di)消电(dian)(dian)子(zi)(zi)(zi)的负空间(jian)(jian)电(dian)(dian)荷(he)作(zuo)用(yong)，使(shi)管子(zi)(zi)(zi)具有电(dian)(dian)流大、内阻低的特点。充气(qi)管内的放(fang)(fang)电(dian)(dian)形式取决于(yu)管子(zi)(zi)(zi)结构、气(qi)体种类、气(qi)压和(he)外电(dian)(dian)路参量。人们利用(yong)各种放(fang)(fang)电(dian)(dian)形式的不同(tong)特性制出一系列(lie)不同(tong)性能(neng)的充气(qi)管。
