Abstract:
1. A hybrid transmission device comprising: a common port; a coplanar waveguide connected on a first end to the common port; a power divider having a first terminal connected to the coplanar waveguide, and having second and third terminals; slotlines, each slotline connected on a first end to a respective one of the second and third terminals of the power divider; terminations provided on the second ends of the slotlines, the terminations formed by openings formed in the metalization region at the second ends of the slotlines to create open circuits; a first differential port; a first microstrip line connected on a first end to the first differential port and connected on a second end by a first microstrip to slotline transition near a second end of a first of the slotlines; a second differential port; and a second microstrip line connected on a first end to the second differential port and connected on a second end by a second microstrip to slotline transition near a second end of a second of the slotlines.
