Patent ID: 8901719

Claim:
A transition from a first planar structure of a chip to a waveguide port, the first planar structure having a first main side and a second main side, wherein the first main side comprises at least one input port arranged to receive an input signal, at least one output port arranged to output an output signal, and at least one electrical functionality, wherein one port of said at least one input port and said at least one output port is electrically connected to an electrically conducting probe that extends directly, without an intervening structure, from said one port to the waveguide port to enable a signal to be transferred between said one port and the waveguide port, and wherein said one port and the electrically conducting probe are formed from the same structure, wherein the first planar structure is mounted to a first base main side of a base structure in the form of a lead frame having said first base main side and a second base main side, wherein the second main side is arranged to face the first base main side, wherein the waveguide port is arranged in the base structure, running from the first base main side to the second base main side.
