Microwave switching with illuminated field effect transistors

Directional coupler in coplanar waveguide technology

Microwave circuit, has defected ground structure filter formed using strip line technology by recess in metallization of rear side of substrate, where pair of signal lines run on front side of substrate and connected with balun

Microstrip line with sections broadened to accept integrated component

Electronic switch uses FET control signal made up at least partly of correction signal generated from switched signal for at least one switch state for frequency-dependent voltage drop compensation

Directional coupler employing coplanar waveguide technology

Coaxial-to-coplanar line-systems connection e.g. for integrated microwave circuits, has coplanar line system fixed via elastic link

Monolithically integrated attenuator for microwave circuit, has three resistors, where frequency response compensation is realized by frequency-dependent loss factor density-profile over cross section of two resistors

Directional coupler in coplanar waveguide technology for measuring applications, has spacing between two internal conductors exponentially increasing at coupling path along longitudinal direction
