Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail: present embodiment implements under the premise of the technical scheme of the present invention, has provided detailed implementation and specific operation process, but protection scope of the present invention is not limited to the following the embodiment.

[0019] Such as figure 1 As shown, this specific embodiment is a 16-way power combiner based on a radial architecture in an eight millimeter wave band. In the embodiment, the E-plane Y branch of the rectangular waveguide integrates eight radially arranged power combiners based on the fan-shaped waveguide, which is denoted as port 1 . The radius of the fan-shaped waveguide is R=6.8mm, and the dimension a of the wide side of the 16-way tapered rectangular waveguide remains unchanged, which is 7.112mm; the dimension of the narrow side is =2.3mm at the junction, and gradually changes to b=3.556mm. In this...

Abstract

The invention provides a novel millimeter wave waveguide radial power synthesis circuit. According to the invention, eight rectangular waveguide Y branches are utilized for integrating eight fan-shaped waveguide based power combiner arranged in radial direction into one. Compared with a traditional round waveguide radial structure based power combiner, the amplitude and phase consistence of branch ports is better. Besides, the circuit has characteristics of small size and wide frequency band and can be used for meeting requirements for millimeter wave multi-channel high-efficient high power synthesis.

Description

technical field [0001] The invention relates to the technical field of microwave and millimeter waves, in particular to the technical field of millimeter wave power synthesis. Background technique [0002] With the in-depth application of microwave and millimeter wave microelectronics technology in the system, the microwave and millimeter wave all-solid-state high-power transmitting system has become the symbol of modern advanced microwave and millimeter wave communication and radar. Generally, there are two main ways to obtain high power of microwave and millimeter waves: vacuum electronic power devices and solid-state power devices. Electro-vacuum devices include traditional klystrons and traveling wave tube power amplifiers. Although they can provide high-power output, they are difficult to realize in the process and cannot be mass-produced. Moreover, the working voltage is very high (tens of kilovolts), and the volume Large, low reliability, short life, low linearity. ...
