Transition from a chip to a waveguide port

A transition according to any one of the preceding claims, characterized in that the first planar structure is a chip (1, 1′, 62) having a plurality of electrical functions, and where bond wires (46) connect chip connections (35, 36, 37, 38, 39, 40, 41, 42, 43, 45) to corresponding package connections (22, 23, 24, 25, 26, 7, 8, 20, 19, 9) comprised in the base structure (5), where the base structure (5) and the chip (1, 1′) at least partly are comprised inside a moulding (32), forming a package with said package connections (22, 23, 24, 25, 26, 7, 8, 20, 19, 9) accessible.

A transition according to any one of the preceding claims, characterized in that an electrically conducting enclosure (49, 49′, 82) is positioned over the waveguide port (47, 47′, 77), such that a cavity (50, 50′, 84) having electrically conducting walls (51, 52, 53, 54, 55;

• 51′, 52′, 53′, 54′, 55′) is formed, enclosing the electrically conducting probe (48, 48′, 73), the dimensions of the cavity (50, 50′, 84) being adapted such that the probe (48, 48′, 73) may transfer a signal to and/or from the waveguide port (47, 47′, 77) in a desired manner.

A package comprising a chip (1, 1′, 62) having a plurality of electrical functions, and where bond wires (46) connect chip connections (35, 36, 37, 38, 39, 40, 41, 42, 43, 45) to corresponding package connections (22, 23, 24, 25, 26, 7, 8, 20, 19, 9) comprised in a base structure (5), where the base structure (5) and the chip (1, 1′) at least partly are comprised inside a moulding (32), forming said package with said package connections (22, 23, 24, 25, 26, 7, 8, 20, 19, 9) accessible, characterized in that the package comprises a transition from the chip (1, 1′, 62) to a waveguide port (47, 47′, 77), the chip (1, 1′, 62) having a first main side (3, 3′, 66) and a second main side (4, 4′, 67), where the first main side (3, 3′, 66) comprises at least one input port (35, 36, 37, 38, 39), arranged to receive an input signal, at least one output port (44, 45;

• 72), arranged to output an output signal, and at least one electrical functionality, where one port (44, 72) of said ports (44, 45;
• 72;
• 35, 36, 37, 38, 39) is electrically connected to an electrically conducting probe (48, 48′, 73) that is arranged to extend from said one port (44, 72) and at least partly over the waveguide port (47, 47′, 77) such that a signal may be transferred between said one port (44, 72) and the waveguide port (47, 47′, 77).
