| Abstract | 论述了一种宽带多孔耦合型定向耦合器，工作频段中心频率为40GHz，相对带宽50%，拟用于射电望远镜Q波段接收机系统。该定向耦合器为一款结构紧凑的器件，采用对称的等间距多孔耦合形式，将主通道圆波导TE11模式信号耦合到耦合通道的矩形波导中，实现了小于-20dB耦合特性。为了对设计进行验证，这里对该定向耦合器进行了加工和测试。测试结果表明，在30～50 GHz工作频段内，主通道反射系数小于-24.2 dB，且全频段内的端口耦合度保持在-20～-21 dB之间。仿真与测试结果具有较高的吻合度，进一步证实了该设计可用于射电天文望远镜的Q波段接收机系统。 |
| Other Abstract | This paper describes a wideband directional coupler based on the multi-hole coupling technique,which is prepared for the Q-band receiver system of radio telescope,the center frequency of this directional coupler is 40 GHz,with a relative bandwidth of 50%. This directional coupler has a compact size,adopting a symmetric and uniformly-spaced form of multi-hole coupling. It couples the TE11 mode signal of the main channel circular waveguide to the coupling channel rectangular waveguide,realizing a coupling characteristic of less than -20 dB. To verify the design,a fabrication is manufactured and measured. The measurements show that in the band of 30-50 GHz,the reflection coefficient for the main channel is less than -24.2 dB,and the port coupling coefficient for the full frequency band is between -20 dB and -21 dB. The simulations are in good agreement with the measurements,which further proves the design can be applied to the Q-band receiver system of radio telescope. |
