Microwave power distributor with multiple power distributing ratios

Abstract

This invention relates to a microwave power splitter having multiple kinds of power splitting ratios, in which, the microstrip lines of said power splitter form a square, every edge of which is connected by two equivalent 1 / 4 wavelength lines, the cross points of two equivalent 1 / 4 wavelength lines at the right and left of the square are connected by an equivalent 1 / 2 line and the property impedance, the electric length and loaded capacitance value are determined by the output power distribution ratio of the power splitter, which gets high isolation without using any isolation resistors and the stationary ratio is good.

technical field

[0001] The invention relates to a microwave power splitter, in particular to a microwave power splitter with a microstrip line in a square structure and utilizing capacitive loading technology with various power distribution ratios. Background technique

[0002] The full name of microwave power divider is microwave power divider, which is widely used in microwave circuits, especially microwave integrated circuits. At present, for small and medium power two-way microwave power splitters, most of them use microstrip three-port power splitters. For a three-port power divider with no loss and reciprocity, it is impossible for the three ports to match at the same time, so the Wilkinson structure is generally used, and isolation resistors are used to improve the isolation between ports and the matching of each port. For multi-channel microwave power splitters, a common method is to use multiple power splitters divided into two for cascading expansion to obtain pow...
