Abstract

The invention relates to a plasma microstrip switch comprising a microstrip transmission line and a plasma generator, wherein the plasma generator clings to a microstrip substrate on a microstrip gap for blocking off an electromagnetic wave and generates a plasma layer with high density distributed along the surface of the substrate so as to completely cover the microstrip gap; and the conductor property of the plasma ensures that the electromagnetic wave which has the frequency lower than that of the plasma and is blocked off by the gap can be transmitted by the gap. A control power source system provides high voltage or zero potential for a discharge electrode of the plasma generator to control the generation and the attenuation of a discharge plasma, thereby controlling the conduction and the disconnection of the microstrip electromagnetic wave and achieving the switching function. The time for the generation and the attenuation of the discharge plasma is preferably in a microsecond, so that the requirement of the high-speed microstrip switch can be met. The invention has the advantages of wide working frequency band, high isolation degree, small insertion loss, high speed and good power property; meanwhile, the plasma microstrip switch has simple structure, feasible process and no mechanical part and can realize complete circuit control.

Description

technical field [0001] The invention relates to a microstrip switch, in particular to a plasma microstrip switch, and belongs to the technical field of microwave circuits. Background technique [0002] Microstrip line is one of the basic devices for microwave transmission and has been widely used in microwave circuits. The microstrip line can be printed on a very thin dielectric substrate, and its cross-sectional size is much smaller than that of the waveguide and the coaxial line, so that the wavelength of the electromagnetic wave on the transmission line is several times smaller than the wavelength of the free space, which better solves the problem of small For the optimization problem, microstrip circuits can be used to transmit electromagnetic signals in a smaller scale. The microstrip switch is the basic component for controlling the transmission of electromagnetic waves in the microstrip, and is used to control the on-off of the circuit, such as solid-state switches s...
