Embodiment Construction

[0036] The radial waveguide synthesis device is a synthesis device based on waveguide space synthesis technology, which can realize the one-time synthesis of output power of multiple modules. It has the characteristics of high synthesis efficiency, wide working frequency band, good amplitude and phase consistency, and small insertion loss. It makes up for the shortcomings of other power combining technologies. At the same time, it can realize the use of other frequency bands by adjusting the size of the device. It has a wide range of applications and works in microwave, millimeter wave and higher submillimeter wave frequency bands. The problem of achieving high power output in higher frequency bands, especially the power synthesis and distribution of high frequency bands can be realized in a small size, the synthesis efficiency is high, and it is suitable for high power synthesis and distribution.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a power combining and distributing device. Background technique [0002] In radar and communication systems, power amplifiers are used more and more widely, but due to limitations in technology and technology, the single-tube output power of power amplifiers is limited, especially in high-frequency power applications. The disadvantages are more obvious. In order to meet the output requirements of high-frequency and high-power signals, a power combining and distributing device must be used. [0003] Traditional binary power distribution devices, such as Wilkinson power splitters and branch line coupling devices, are only used for small power synthesis, and are combined step by step. capacity needs. The waveguide T-junction power combination and distribution device for high-power applications also needs to be combined step by step, the combination effici...
