A sampling circuit for microwave signals includes a substrate (S), a planar microwave guide (PL) on one side of the substrate and a conductive surface on the other. A slotline is formed by a rectangular insulating area (B) on the other side, and a drive pulse conductor (KX) is connected to opposite edges of the insulating area for supplying the sampling pulses. On one side of the substrate there are two separate conductive surfaces (A1,A2), which together with the conductive surface (A) on the other side forms the capacitors included in the sampling circuit. Two discrete diodes (D1,D2) are connected between the microwave guide and the respective surface (A1,A2), and resistors (R1,R2) are connected between these surfaces and planar output waveguides (UL1,UL2) for the sampling circuit. |
