Abstract

The invention provides a small-size ultra wideband power divider, comprising a circuit board and a power division circuit arranged on the circuit board, wherein the power division circuit is provided with an input signal transmission segment connected to an input port and two output signal transmission segments connected to an output port, the input signal transmission segment and the output signal transmission segments are electrically connected by a circuit node, signal transmission path lengths of the input signal transmission segment and the output signal transmission segments are 1 / 6 lambda to 1 / 9 lambda, and a circuit matching segment used for matching line impedance and having a signal transmission path length of1 / 3 lambda to 1 / 6 lambda is further connected at the circuit node of the input signal transmission segment and the output signal transmission segments. The size of the power divider is reduced, so the power divider can be applied to more environments. The problems of line capacitance and inductance effects and impedance mismatch resulting from a shortened signal transmission branch length are overcome, and the performance of the power divider is guaranteed.

Description

technical field [0001] The invention relates to a power divider for an antenna, in particular to a small-sized ultra-wideband power divider. Background technique [0002] The full name of the power divider is the power divider, which is a device that divides the energy of one input signal into two or multiple outputs with equal or unequal energy, and is the basic element in the antenna array feeding network. With the development of technology, people's requirements for the miniaturization of devices are getting higher and higher, and the miniaturization and broadband of power dividers have always been the research directions in the industry. Impedance matching is a common working state in radio technology, which reflects the power transfer relationship between the input circuit and the output circuit. Maximum power transfer is achieved when the circuit is impedance matched. Conversely, when the impedance of the circuit is mismatched, not only the maximum power transfer can...
