Abstract

The present invention discloses an ultra wide band transmission-line transformer 3-path composite structure. The structure comprises a balance resistor, 3-path transmission-line transformers respectively communicating with 3-path signals, and a star-like structure formed by the balance resistor and the 3-path transmission-line transformers; the balance resistor comprises 3-path resistors connectedin series end to end, nodes of adjacent resistors are respectively electrically connected with corresponding terminals of the 3-path transmission-line transformers, the output terminals of the 3-pathtransmission-line transformers are subjected to impedance change through unbalanced transmission-line transformers and then output, and three-path input terminals of the 3-path transmission-line transformers are configured to communicate with 3-path signals. The ultra wide band transmission-line transformer 3-path composite structure is high in combination success rate little in insertion loss, small in size and general in interface, can perform magnet ring regulation by users according to the combination success rate demands themselves so as to fit the combination success rates and the product sizes of the users themselves.

Description

technical field [0001] The invention relates to a three-way synthesizing structure of an ultra-wideband transmission line transformer, which is used for synthesizing and distributing power, and belongs to the field of radio frequency broadband synthesizing. Background technique [0002] With the development of radio communication technology, especially the rapid development of communication technology in recent years, the requirements for power combination technology are getting higher and higher, especially for broadband high-power combination technology, which needs to be improved urgently. With the development of communication technology, the demand for high-power, small-volume, and broadband power amplifiers is becoming stronger and stronger. However, limited by the power device semiconductor technology, the output power and bandwidth of a single power device are always contradictory. Synthesizers present a real need. Only by combining the output power of multiple power...
