衰减器

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.
