TRANSMISSION LINE Russian patent published in 2001 - IPC

FIELD: electronics, microelectronics. SUBSTANCE: transmission line can include modulators and switches. Transmission line incorporating several two-wire transmission lines which have one common conductors and other conductors have different lengths, being connected either to conductive sections or having gaps with reference to conductive sections forming ohmic contact with semiconductor layers of electron or hole conduction type with formed nonrectifying contact. Conductive sections are manufactured either at start or at end of transmission line. Surface of layer has semiconductor or metal layer with another nonrectifying contact forming with film p-n junction or Schottky barrier with impurity profile inhomogeneous along direction of crossing of sections. If conductors are laid with gap relative to conductive sections another semiconductor layer of electron or hole conduction type with formed nonrectifying contact is deposited and p-n junction or Schottky barrier with impurity inhomogeneous profile with nonrectifying contact crossing sections is formed. In this case selection of wave resistance and length of line is determined by values of voltages across p-n junctions or/and Schottky barriers. EFFECT: construction of transmission line with wave resistance and length adjusted with use of external electric voltage. 5 cl, 15 dwg
