Tnc系列产品是一种螺纹连接式射频同轴连接器，它具有工作频带宽、连接可靠、抗振性能良好等特点，可供无线电设备和仪器中连接电缆用。 - Electromagnetic compatibility and radio spectrum matters - maritime mobile earth stations operating in the 1 , 5 ghz and 1 , 6 ghz bands providing voice and direct printing for the global maritime distress and safety system - technical characteristics and methods of measurement v1 . 1 . 1
电磁兼容性和无线电频谱情况.全球海上遇险呼救与安全系统用提供声音和直接打印的工作频带为1 . 5ghz和1 . 6ghz的海上移动地面站.技术特性和测量方法 - The author ? major contributions are as follows . 1 . with the performance requirement ( the pattern of the antenna , the rang of scanning angle , the maximal sidelcbe level and the beam ~ vidth ) givcn , a method is presented to determine the basic parameters of a serpentine feed , which includes the distance and ~ vaveguide length bet ~ veeii t ~ vo couplers , the size of the arrays and the number of components
根据天线的工作频带、扫描范围、副瓣电平、半功率宽度等技术指标要求，给出了确定波导慢波线基本结构尺寸的计算公式，即对相邻单元之间的空间距离、耦合器之间的馈线波导长度、阵列的大小和单元数的计算。 - Compare to the normal rectangular waveguide , ridge waveguide has the character of broader bandwidth , smaller dimension , lower equivalent characteristic impedance , etc . because of these merits , it is used more and more widely , such as broadband ridge waveguide filter , broadband direct coupler , diplexer , frequency converter , phase shifter , ridge waveguide slot antenna array , and so on
与普通矩形波导相比，脊波导具有工作频带宽、尺寸小、等效特性阻抗低等特点。由于脊波导本身的特点，使其得到了越来越多的应用，例如宽带脊波导滤波器、宽带定向耦合器、双工器、变频器、移相器、脊波导缝隙天线阵等等。 - The lowest validity returns to put the frequency with tallest the validity return to put the between frequency scope . general circumstance bottom , person can that hear signal about is 20 hz enlarging of 20 signal for variety signal for of form , different range of different frequency , different wave , for this reason enlarger wanting nicely completing the work , must have the enough breadth to take
最低有效回放频率与最高有效回放频率之间的范围。一般情况下，人能听到的音频信号大约是20hz 20khz之间的不同频率不同波形不同幅度的变化信号，因此放大器要很好地完成音频信号的放大，就必须有足够宽的工作频带。
