本文介绍了一种简单的波导定向耦合器,它采用了毫米波器件中常见的分块式结构。耦合器使用一系列悬挂在石英支架上的金属探针。取决于耦合元件的数量,耦合可以在15-30 dB的范围内,在整个波导频带上通常具有± 2 dB的变化,并且方向性> 10 dB。耦合器,旨在注入本地振荡器功率到波导混频器,可以缩放在任何波导波段的操作。
A simple waveguide directional coupler is described which uses the split-block type of construction common in millimeter-wave components. The coupler uses an array of metal probes suspended on quartz stand-offs. Depending on the number of coupling elements, the coupling can be in the range 15-30 dB, with typically ± 2 dB variation across the waveguide band, and directivity > 10 dB. The coupler, intended for injecting local oscillator power into a waveguide mixer, can be scaled for operation in any waveguide band.
