Abstract

In this paper, 4 different crossover structures in a 6-
layered printed circuit board (PCB) for high operation frequencies
are presented. The design for all structures is based on grounded
coplanar waveguide (GCPW). Two fully planar structures, a
quasi-coaxial transition and coaxial transition are realized and
have a measured bandwidth from DC to 50 GHz and DC to
60 GHz, respectively. Moreover, two structures are designed in
submount technology. Especially the connection between baseboard
and package (solder junction) plays an important role to
guarantee best signal integrity. Therefore, the quality of the solder
junction is analysed in detail with TDR (time domain reflectometry)
measurement as well as with X-ray images. The submount
transitions show good radio frequency (RF) characteristics from
DC to 70 GHz.
