RADIO FREQUENCY FEEDTHROUGH

摘要

A radio frequency feedthrough for optoelectronic housings is provided that includes a multilayer ceramic body and a signal conductor that extends through the ceramic layers in an S-shape. In an upper region of the multilayer ceramic body, a ground layer is recessed in a V-shape, and in a central region of the multilayer ceramic body the signal conductor extends coaxially.

主权项

1. An SMD compatible feedthrough for radio frequency signals, comprising:
a multilayer ceramic body; at least one signal conductor extending through the multilayer ceramic body; a first, lower terminal; and a second, upper terminal spaced in a vertical direction from the first, lower terminal, wherein the multilayer ceramic body has layers and ground layers, the ground layers having a recess around the at least one signal conductor and being connected to each other by ground vias extending through the layers, and wherein, in the ground layer of the second, upper terminal, the recess around the signal conductor widens behind an end of the second, upper terminal.
