High-power distributor/synthesizer

Abstract

The invention discloses a high-power distributor / synthesizer, belonging to the field of communication. The high-power distributor / synthesizer is characterized in that each input interface is connected with a first high-frequency board; every two adjacent first high-frequency boards form a group for synthesis, and a resistor is arranged between and connected with the two first high-frequency boards in the same group; and the two first high-frequency boards in the same group are separately connected with the same second high-frequency board through inductors, and all the high-frequency boards are connected in the same mode until input signals are combined into one path. According to the high-power distributor / synthesizer, the plurality of high-frequency boards are connected through the resistors and the inductors, so power generation, synthesis and distribution are achieved; lumped parameter capacitors are replaced by the high-frequency boards, so cost can be reduced, the size of the capacitors can be freely configured according to requirements, design and manufacturing of the power distributor / synthesizer are greatly facilitated, and a structure is more compact; and in addition, due to the fact that the heat dissipation area of the high-frequency boards in the design is large and a signal transmission line is wide, high-power transmission can be achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a high-power distribution / synthesizer of HF and VHF frequency bands. Background technique [0002] In a solid-state transmitter, the power distribution / combiner is an indispensable part. There are many types of power distribution / combination technologies, generally including Wilkinson, microstrip coupling, balun transformer, T-junction power division, and space synthesis technology. [0003] In the HF and VHF frequency bands, due to the long signal wavelength, the microstrip and space synthesis methods take up a lot of space and are not suitable for application in equipment. Lumped parameter components are generally used to implement power distribution / synthesizers in the HF and VHF frequency bands. Traditionally, Wilkinson and Balun, which are composed of lumped parameter elements, realize power synthesis and distribution in the VHF frequency band. [0004] Under general power transmi...

Problems solved by technology

However, as the signal transmission power increases, if a balun is used to achieve power synthesis and distribution, the volume of the high-permeability and low-loss magnetic core used to construct the balun circuit will increase with the increase of the transmission power, and the weight will also increase. The larger the size, the inconvenience of fixed installation and the higher cost of use will be brought. For example, the Wilkinson built with inductors and capacitors is used to realize power synthesis and distribution. The requirements for capacitors become higher and higher with the increase of transmission power. The pressure resistance also needs to be larger and larger. When the transmission power exceeds 5kW, the capacitors selected need special capacitors to participate in the design. The cost of engineering implementation is too high, and the risk of implementation is also increased.
