HIGH-FREQUENCY PHOTOELECTRIC DETECTOR ENCAPSULATION BASE ENCAPSULATED BY ADOPTING MULTI-LAYER CERAMIC TIN |
摘要 |
The present invention applies to the technical field of photoelectric detectors and provides a high-frequency photoelectric detector encapsulation base can-packaged by using a multi-layer ceramic, comprising a laminated multi-layer ceramic substrate, wherein the multi-layer ceramic substrate is welded with pins at a bottom and provided with a metal ring at a top; an upper surface and a lower surface of each layer of the ceramic substrate are both plated with a conductive metal layer; circuit connection holes are distributed in each layer of the ceramic substrate; the upper surface of the multi-layer ceramic substrate is provided with two power contacts and two differential signal contacts; and the power contacts and the differential signal contacts penetrate through each layer of the ceramic substrate to be connected to the corresponding pins. The photoelectric detector encapsulation base is a tank-type base of a multi-layer ceramic structure, the upper and lower surfaces of each layer of the ceramic substrate are electroplated with a conductive metal layer to constitute a co-plane waveguide structure; and a differential signal transmission design being adopted in a high-speed signal line can solve the transmission problem of a signal of higher than 20 GHz in bandwidth, with a small transmission loss. |
