Abstract (en)

The invention is a phase shifter (26) that does not suffer from metallic contact and corrosion problems and that is linear (in high power circuitry/devices), light weight and inexpensive with minimal insertion and return losses. The phase shifter is a stripline structure comprising a first signal board (34) having an input signal line and an output signal line and a second signal board (36) having a U-shaped signal line. The U-shaped signal line is configured to complete a signal trace between the input signal line and the output signal line when the second signal board is positioned a distance D over the first signal board using a slidable mounting system (31, 32). The distance D is a distance sufficient to enable electrical coupling between the U-shaped signal line and the input and output signal lines. The slidable mounting system allows for variations in the signal trace. <IMAGE>
