嵌入式隔离器(qi)(qi)(qi)实现单向(xiang)传(chuan)(chuan)(chuan)输的(de)原理主(zhu)要(yao)是(shi)利用了(le)电(dian)磁波(bo)的(de)相位(wei)差(cha)和衰减(jian)(jian)特性。在隔离器(qi)(qi)(qi)的(de)输入端(duan)，射频信(xin)(xin)号(hao)(hao)(hao)通(tong)(tong)过(guo)天线接(jie)收(shou)后(hou)(hou)，经(jing)过(guo)隔离器(qi)(qi)(qi)内部的(de)滤波(bo)器(qi)(qi)(qi)和放大器(qi)(qi)(qi)处理，然(ran)后(hou)(hou)通(tong)(tong)过(guo)一(yi)个(ge)(ge)耦合(he)器(qi)(qi)(qi)将(jiang)信(xin)(xin)号(hao)(hao)(hao)分(fen)为两路(lu)。其(qi)(qi)中一(yi)路(lu)信(xin)(xin)号(hao)(hao)(hao)通(tong)(tong)过(guo)一(yi)个(ge)(ge)反向(xiang)器(qi)(qi)(qi)，使(shi)得(de)其(qi)(qi)相位(wei)发生变化，再经(jing)过(guo)一(yi)个(ge)(ge)衰减(jian)(jian)器(qi)(qi)(qi)，使(shi)得(de)其(qi)(qi)幅(fu)度(du)减(jian)(jian)小(xiao)，通(tong)(tong)过(guo)一(yi)个(ge)(ge)匹配网络将(jiang)信(xin)(xin)号(hao)(hao)(hao)传(chuan)(chuan)(chuan)输到(dao)(dao)负载(zai)上。另(ling)一(yi)路(lu)信(xin)(xin)号(hao)(hao)(hao)则直(zhi)接(jie)通(tong)(tong)过(guo)一(yi)个(ge)(ge)衰减(jian)(jian)器(qi)(qi)(qi)，幅(fu)度(du)也减(jian)(jian)小(xiao)，然(ran)后(hou)(hou)通(tong)(tong)过(guo)一(yi)个(ge)(ge)正向(xiang)器(qi)(qi)(qi)，使(shi)得(de)其(qi)(qi)相位(wei)发生变化，通(tong)(tong)过(guo)匹配网络将(jiang)信(xin)(xin)号(hao)(hao)(hao)传(chuan)(chuan)(chuan)输到(dao)(dao)负载(zai)上。由于两路(lu)信(xin)(xin)号(hao)(hao)(hao)的(de)相位(wei)相反，因此在负载(zai)上得(de)到(dao)(dao)的(de)信(xin)(xin)号(hao)(hao)(hao)是(shi)相互抵(di)消的(de)，从而实现了(le)隔离器(qi)(qi)(qi)的(de)单向(xiang)传(chuan)(chuan)(chuan)输功能。同时(shi)，由于衰减(jian)(jian)器(qi)(qi)(qi)的(de)使(shi)用，使(shi)得(de)信(xin)(xin)号(hao)(hao)(hao)在传(chuan)(chuan)(chuan)输过(guo)程中能量损失较小(xiao)，提高了(le)传(chuan)(chuan)(chuan)输效率(lv)。深圳四端(duan)口环(huan)形(xing)器(qi)(qi)(qi)批发厂(chang)家环(huan)行器(qi)(qi)(qi)典型用于：收(shou)发信(xin)(xin)号(hao)(hao)(hao)公用天线。

同(tong)(tong)(tong)轴(zhou)(zhou)环行(xing)器(qi)(qi)(qi)的(de)工(gong)作原理(li)是基(ji)于(yu)磁(ci)场的(de)不对(dui)称传输(shu)(shu)(shu)(shu)(shu)。当(dang)信(xin)号从一(yi)个(ge)方(fang)(fang)向进入同(tong)(tong)(tong)轴(zhou)(zhou)传输(shu)(shu)(shu)(shu)(shu)线时，磁(ci)性(xing)(xing)(xing)(xing)材(cai)料(liao)将信(xin)号引导到另一(yi)个(ge)方(fang)(fang)向并将其(qi)隔(ge)(ge)(ge)离(li)(li)。由于(yu)磁(ci)性(xing)(xing)(xing)(xing)材(cai)料(liao)只作用(yong)于(yu)特(te)定(ding)方(fang)(fang)向的(de)信(xin)号，同(tong)(tong)(tong)轴(zhou)(zhou)环行(xing)器(qi)(qi)(qi)可以(yi)(yi)实(shi)现(xian)信(xin)号的(de)单向传输(shu)(shu)(shu)(shu)(shu)和(he)隔(ge)(ge)(ge)离(li)(li)。同(tong)(tong)(tong)时，由于(yu)同(tong)(tong)(tong)轴(zhou)(zhou)传输(shu)(shu)(shu)(shu)(shu)线内外(wai)(wai)导体的(de)特(te)殊(shu)特(te)性(xing)(xing)(xing)(xing)和(he)磁(ci)性(xing)(xing)(xing)(xing)材(cai)料(liao)的(de)影响，同(tong)(tong)(tong)轴(zhou)(zhou)环行(xing)器(qi)(qi)(qi)可以(yi)(yi)实(shi)现(xian)低(di)插入损(sun)耗和(he)高(gao)(gao)隔(ge)(ge)(ge)离(li)(li)。同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)有(you)几个(ge)优点。首先，它具(ju)有(you)低(di)插入损(sun)耗，这减少了信(xin)号衰减和(he)能量损(sun)失。其(qi)次，同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)具(ju)有(you)高(gao)(gao)隔(ge)(ge)(ge)离(li)(li)性(xing)(xing)(xing)(xing)，可以(yi)(yi)有(you)效隔(ge)(ge)(ge)离(li)(li)输(shu)(shu)(shu)(shu)(shu)入和(he)输(shu)(shu)(shu)(shu)(shu)出(chu)信(xin)号，避免相(xiang)互干(gan)扰。此外(wai)(wai)，同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)耐高(gao)(gao)功(gong)率(lv)，适用(yong)于(yu)高(gao)(gao)功(gong)率(lv)应用(yong)。同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)广泛应用(yong)于(yu)各(ge)种射频和(he)微(wei)波(bo)系统(tong)(tong)中。在通信(xin)系统(tong)(tong)中，同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)通常用(yong)于(yu)隔(ge)(ge)(ge)离(li)(li)不同(tong)(tong)(tong)设(she)备之间的(de)信(xin)号，以(yi)(yi)防(fang)止回(hui)声(sheng)和(he)干(gan)扰。在雷达(da)系统(tong)(tong)和(he)天线系统(tong)(tong)中，同(tong)(tong)(tong)轴(zhou)(zhou)循(xun)环器(qi)(qi)(qi)用(yong)于(yu)控制信(xin)号的(de)方(fang)(fang)向并隔(ge)(ge)(ge)离(li)(li)输(shu)(shu)(shu)(shu)(shu)入和(he)输(shu)(shu)(shu)(shu)(shu)出(chu)信(xin)号，以(yi)(yi)提高(gao)(gao)系统(tong)(tong)性(xing)(xing)(xing)(xing)能。
