RF & wireless devices are equipped with many RF signal paths between input and output ports that need to undergo vigorous and complex testing." style="padding: 0px; margin: 0px auto; font-family: Arial, 宋体; font-size: 14px; line-height: 26px;">今天的射频与无线设备都配备了需要经受剧烈和复杂的测试输入和输出端口之间的许多RF信号的路径。因此，使用同轴开关的是在允许用户容易地I / O端口之间切换，并避免具有断开和重新连接射频电缆的麻烦的任务必需的。RFVU"s and maintaining high insertion loss repeatability between ports, makes the life of a RF switch and its reliability imperative." style="padding: 0px; margin: 0px auto; font-family: Arial, 宋体; font-size: 14px; line-height: 26px;">更重要的是，重复整个DUT的射频测试和维护端口之间高插入损耗重复性，使得RF开关的寿命和可靠性至关重要。具有更好的插入损耗可重复性的测定精度增加如在测量路径减小误差的来源。道琼斯键微波炉推出，以满足在执行一个成功的射频测试这些功能的新产品线。
