TRANSMISSION LINE Russian patent published in 1998 - IPC

FIELD: electronics, microelectronics. SUBSTANCE: invention may be used while designing transmission lines with adjustable wave impedance and length. Two-wire line has two conductive strips between which insulating or semi-insulating layer is formed. It is vital that either upper strip has holes along length of line or lower strip has holes transverse to length of line. P-n junction or Schottky barrier having inhomogeneous doping profile along width of upper strip or along length of lower strip is formed on surfaces of strips with holes. Parameters of transmission line (wave impedance and length) are determined by value of controlling external bias fed to p-n junction (Schottky barrier) or by values of controlling external biases fed to p-n junctions or Schottky barriers. EFFECT: improved functional characteristics of transmission line. 8 dwg
