Broadband planar integration and packaging for millimeter-wave circuit design at the V-band

A broadband planar integration and packaging of millimeter-wave circuits based on the integrated waveguide (IWG) and grounded coplanar waveguide (GCPW) transitions are proposed and demonstrated at the V-band. A novel wideband microstrip-line-to-IWC transition is proposed for the planar integration of the rectangular waveguide devices and the insertion loss per one transition is less than 0.1 dB from 43 to 73 GHz. A proposed surface-mountable filter has an insertion loss of 3 dB and a 3.3% bandwidth at a center frequency of 62 GHz. A broadband ribbon interconnection exhibits law loss of 0.2 dB from DC to 70 GHz and the insertion loss of a single microstrip-to-waveguide transition is less than 0.4 dB from 50 to 75 GHz.
