Abstract A new type of solid-state microwave power rectifier is proposed. A section of microwave transmission line is continuously loaded with a piece of long silicon pn junction in a distributed parameter fashion. Suggested configurations would be either a planer stripline type or a coaxial line type. To the microwave input side of the power rectifier, a continuous impedance matching circuit is attached. The d.c. output can be tapped off from any point of the distribution parameter microwave power rectifier. Various feeding and loading configurations are possible, including both the longitudinal and transverse feed and the waveguide feed. Theoretical equations on efficiency and power-handling capacity are introduced, based on a time-and-space averaging principle of the microwave transmission line current with a newly introduced d.c. equivalent electromotive force concept. For example, 2000 watts input at 3000 MHz, on a 10-cm-long silicon pn junction stripline power rectifier with a characteristic impedance of 4 ohms, would produce 42.5 amperes d.c. current for a 1-ohm load with 1800 watts output giving 90percent efficiency.
