Abstract

The device has adjacent coupled lines with an asymmetrical connection gate and two symmetrical connection gates. It has three adjacent lines. One end of the center line forms the asymmetrical gate. The adjacent ends of the outer lines are at earth potential. Both other ends of the outer lines are at earth potential and the center line is free at that point. Each of the two outer lines is interrupted centrally with two symmetrical gate connections. The device consists of several adjacent coupled planar lines (1-3) with an asymmetrical connection gate (TU) and two symmetrical connection gates (TS1,TS2) . It has three adjacent lines, whereby one end of the center line forms the asymmetrical connection gate and the adjacent ends of the outer lines are at earth potential. Both other ends of the outer lines are likewise at earth potential and the center line is fee at that point. Each of the two outer lines is interrupted at the half way point and at this point has two connections for a symmetrical connection gate.
