Abstract

The invention discloses a novel ultra-wideband microstrip Wilkinson power splitter, which belongs to the field of microwave engineering. It includes one input port and n output ports, m isolation resistors are set between the two adjacent output ports, and multi-section impedance converters are set between the input port and n output ports, each section The impedance converter is a quarter-wavelength impedance line; the isolation resistance Rki between the k-th output port and the k+1 output port and the isolation resistance R between the k-1 output port and the k-th output port ( There is an interval L between k-1) i, and 0<L<1 / 4λ, i=1, 2, 3..., m, k=2, 3..., n-1. The power divider of the invention can realize the average distribution of power within 1-8GHz, and each port is well matched, each output port is well isolated, the return loss is low, and the output phase amplitude consistency is high.

Description

technical field [0001] The invention belongs to the field of microwave engineering, and in particular relates to a novel ultra-wideband microstrip Wilkinson power divider. Background technique [0002] A power divider (referred to as a power divider) refers to a device that can divide an input signal into two or more output signals that are the same or different. It can realize the distribution / combination of multiple electromagnetic signals. The missing functional unit, in addition to the commonly used two-way power splitter, often requires other power splitters, such as three-way power splitters, in the antenna array feed network and power combining circuit. In occasions that do not require high power capacity, microstrip line three-way power dividers have been widely used in mobile communications, aerospace, radar detection and other fields due to their advantages of light weight, low cost, and simple structure. [0003] According to different circuits, power dividers ca...
