Abstract

The invention discloses a power divider with frequency reconfigurable in a wide range. The power divider comprises a Wilkinson power divider unit, a pi-shaped circuit structure based on voltage regulation, microstrip transmission lines, a medium substrate and a floor metal layer. The power divider with frequency reconfigurable in the wide range provides signals having equal power at two output ports, is simple in structure, is easy to process and integrate, and is small in size. The power divider with frequency reconfigurable in the wide range can well meet performance demands of the power divider in working frequency regions.

Description

technical field [0001] The invention relates to a power distribution and power synthesis device of the radio frequency front end of the fifth generation mobile communication, in particular to a reconfigurable power distributor with adjustable operating frequency in a wide range. Background technique [0002] The fifth-generation mobile communication system is a national strategic high-tech industry, a typical technology-intensive and service-oriented IT industry, and its development prospects are very broad. It is the fastest-growing information industry in the world after cellular mobile communication and the Internet. Many countries and organizations are vigorously researching the fifth generation mobile communication system. The fifth-generation mobile communication system has become the focus of research in the field of mobile communication at home and abroad. In early 2013, the European Union launched the METIS (mobile and wireless communications enablers for the 2020in...
