The invention solves many defects such as large loss, large actual size and narrow working bandwidth of the existing power divider.

Description

technical field [0001] The invention belongs to the technical field of ultra-wideband mobile communication, and in particular relates to a power divider. Background technique [0002] At present, ultra-wideband technology is a new and efficient communication method that can alleviate the problem of crowded frequency resources. This technology has been gradually used in the new generation of wireless communication technologies such as WLAN and GPS. The power divider is a common passive module in the communication system. The traditional equal-divided power divider is mainly composed of multiple quarter-wavelength impedance lines. There are resistor terminals at the nodes of each impedance line. The more nodes used , the more the isolation resistance is, the correspondingly wider bandwidth and better isolation can be obtained. However, increasing the resistance will increase the parasitic loss, and increasing the number of nodes will increase the component size. Therefore, t...
