Abstract: An ultra-wideband radio-frequency bidirectional coupler with power divider/combiner functionality (200A, 200B, 300, 400A, 400B, 400C) for signals with frequency reaching up to 300 GHz, a free propagation region substrate (210) with a pair of opposed edges (240A, 240B), a first group of access ports (P-L1-P-LM) established along the at least one edge of said free propagation region substrate (210); and a second group of access ports (P-R1-P-RM) established along the opposite edge of said free propagation region substrate (210), wherein the first and second groups of access ports (P-L1-P-LM), (P-R1-P-RN) comprise dielectric waveguide structures (DW-L1-DW-LM), (DW-R1-DW-RN) providing a high-pass characteristic interconnect operating over a high frequency range starting from a low cut-off frequency fCL in the microwave range or in the millimeter-wave range.

Abstract: A ultra-wideband interconnection probe (100) connectable to a first access port of a first electronic device (101), the first access port comprising a first tapered coupler (101a) and to a second access port of a second electronic device (102), the second access port comprising a second tapered coupler (102a), the ultra-wideband interconnection probe (100) comprising a dielectric waveguide structure (120) establishing a high-pass characteristic interconnect, operating over a high frequency range starting from a low cut-off frequency fa in the microwave range or in the millimeter-wave range, wherein the dielectric waveguide structure (120) comprises a first tapered end (120a) connectable to the first access port via the first tapered coupler (101a) and a second tapered end (120b) connectable to the second access port via the second tapered coupler (102a).
