微槽——微带定向耦合器是微带定向耦合器的一种变型。它具有十个倍频程以上的特宽频带和较强的耦合度等特点,制造工艺也不太复杂,是实现宽频带定向耦合器的一种新方案。××厂正在试制的××微波测量仪器新产品中需用频率从1—12,4~(Gc)、耦合度约6~(db)的定向耦合器,组成宽频带微波混频器。结合该项任务,对微槽——微带这种宽频带定向耦合 Micro-slot - microstrip directional coupler microstrip directional coupler is a variant. It has more than ten times the octave band of extra wideband and strong coupling and so on, the manufacturing process is not too complicated, is to achieve a wideband directional coupler a new program. × × plant is trial production of ×× microwave measuring instruments need to use the frequency of 1-12,4 ~ (Gc), the coupling degree of about 6 ~ (db) directional coupler to form a broadband microwave mixer. In conjunction with this task, a microgroove-microstrip broadband coupling is achieved
