ABSTRACT:
A chain amplifier assembly, includes a semiconductor body, a chain amplifier disposed in the semiconductor body and having an input, an output, a plurality of interconnected amplifier stages having transition regions therebetween, each of the stages including a plurality of field-effect transistors having source, gate and drain terminals, each of the source terminals being connected to a given common source potential, a plurality of ohmic resistors and inductances connected in series between the gate terminals forming a gate line, a plurality of capacitances each having a lead connected in parallel to the gate line and another lead connected to the given common source potential, a plurality of inductances connected in series between the drain terminals forming a drain line, a plurality of additional ohmic resistors having a lead connected in parallel to the drain line and another lead connected to the given common source potential, a plurality of additional capacitances having a lead connected in parallel to the drain line and another lead connected to the given common source potential, matching elements in the form of capacitances, inductances and ohmic resistors connected at the input, output and transition regions, the drain and gate lines being wave guides formed with metal coatings, insulating coatings and doping concentrations required for the field-effect transistors, and additional circuit elements monolithically integrated into the semiconductor body.
