3dB电桥功分器
摘要：
本发明提供一种3dB电桥功分器，包括四个端口，分别为输入端口、0度输出端口、90度输出端口和隔离端口，所述输入端口与0度输出端口之间和所述90度输出端口与隔离端口之间分别设有微带线，所述输入端口、0度输出端口和设置于所述输入端口与0度输出端口之间的微带线位于第一平面内，所述90度输出端口、隔离端口和设置于所述90度输出端口与隔离端口之间的微带线位于第二平面内，所述第一平面和第二平面不共面。本发明提供的3dB电桥功分器能够减小微带线所占的横向面积，有效地增加了该3dB电桥功分器的空间利用率。
摘要（英）：

The invention provides a 3dB bridge power divider, comprising four ports which are respectively an input port, a 0-DEG output port, a 90-DEG output port and an isolation port, wherein a microstrip line is arranged between the input port and the 90-DEG output port and a microstrip line is arranged between the 0-DEG output port and the isolation port, the 3dB bridge power divider also comprises a plurality of capacitors, and the plurality of capacitors are arranged between the input port and the 90-DEG output port as well as between the 0-DEG output port and the isolation port. The 3dB bridge power divider can play an effect of adjusting the working frequency thereof through arranging the capacitors between the input port and the 90-DEG output port as well as between the 0-DEG output port and the isolation port, and can be applied on a magnetic resonance variable-frequency multi-channel emission system.
