在通信、电视广播、很多电子设备与仪表中需要使用各种形式的宽频带变压器,其作用在于实现阻抗匹配,隔除直流,连接对称与不对称电路,获得精确的电流电压比等,这些作用往往是其他电子部件无法代替的。由于宽频带变压器的工作频率比较高、频带宽,作为一个重要部件,要满足必要的技术指标常常相当困难,在很多情况下,如何 In communications, television broadcasting, many electronic devices and meters need to use various forms of broadband transformers, whose role is to achieve impedance matching, cut off DC, connecting symmetrical and asymmetrical circuits, to obtain accurate current and voltage ratio, these effects Often other electronic components can not be replaced. As the broadband frequency transformer operating frequency is relatively high, bandwidth, as an important component, to meet the necessary technical indicators are often quite difficult, in many cases, how
