Abstract

The invention discloses a four-way power combiner for a pair-pole fin line millimeter wave waveguide. The four-way power combiner comprises two rectangular waveguides, wherein metal brackets are arranged in the rectangular waveguides, pair-pole fin lines are arranged on the upper layers and the lower layers of the metal brackets, and the pair-pole fin lines in the two rectangular waveguides are connected through microstrip lines. The four-way power combiner is simple in structure, easy to manufacture, small in insertion loss and return loss, high in way isolation, capable of providing good heat dissipation characteristics and has the potential for large-scale space power combination.

Description

technical field [0001] The invention relates to a power combiner, in particular to a four-way power combiner with dipole-fin line millimeter-wave waveguides. Background technique [0002] With the development of wireless communication technology and microwave engineering technology, microwave and millimeter wave hybrid integrated circuits have been widely used, especially the millimeter wave frequency band, which has become the main frequency band for the development of military electronic technology, widely used in precision guidance, radar, Electronic countermeasures and measurement testing and other fields. In systems such as millimeter-wave electronic countermeasures, the wider the working bandwidth of the millimeter-wave power transmitter that meets a certain output capability, the better. Power amplifier is one of the important components of millimeter wave transmitter. With the development of semiconductor and monolithic integrated circuit technology, the application...
