According to the items and the costs, three kinds of diplexers with different configurations are designed, named parallel coupled, interdigital , and SIR.

针对公司提出的性能指标和制作成本的要求,设计了三种结构(平行耦合、交指、SIR)的双工器

The size of the diplexer was 18.3mm×15.6mm×0.5mm, at the frequency of 1.87GHz and 2.34GHz, the decay was higher than 55dB, so it suppressed the local oscillator signal and its mage reconstructor tube signal effectively, which met the design of filter with miniaturization. And then the three-dimensional laminated structures were used to realize the design of miniaturization, which was good for the later research.
