Problems solved by technology

The disadvantages are: 1. When the number of synthesis / distribution channels is large, the number of stages increases and the loss becomes larger
2. The number of synthesis paths must be an integer multiple of 2, not any number of paths
The disadvantage of this kind of synthesizer / distributor is that when the number of synthesizers exceeds three, the structure will be difficult to realize
Due to the limited power bearing capacity of the printed board itself, the power capacity of the synthesizer / distributor of this structure is not large

Embodiment Construction

[0027] Structure and working principle of the present invention are described in detail as follows in conjunction with each accompanying drawing and embodiment:

[0028] The electrical principle diagram of the present invention is as figure 2 As shown, n channels of power combiner input / distributor output (P1,...Pn) are connected to combiner power output port / distributor power input port through n quarter-wavelength transmission lines (L1,...Ln) connected. The n channels of power input / output (P1,...Pn) are also connected to n loads (R1,...Rn) via n quarter-wavelength transmission lines (M1,...Mn). n loads (R1,...Rn) are connected together via another n quarter-wavelength transmission lines (K1,...Kn).

[0029] The overall structure of a four-way power combiner / distributor designed in this embodiment is as follows Figure 4 As shown, it mainly includes two cover plates 501, 503 (such as Figure 5 shown), a front end plate 407, a rear end plate 408, a middle partition plat...

Abstract

The multiplexing compositor / allotter includes the fractional power input / output ports module, the connection load port module, the closed case, the transmission line module and the electrical connection module. The multiple cavities cascaded constitute the closed case. Each cavity is composed of the ambient side plates and one piece of the metal clapboard. The three sections of quarter-wave transmission line constitute one or two transmission lines. The joint point of the first section and the second section through the transmission line is connected to the load port module. Each transmission line module is suspended in the cavity respectively. The electrical connection module at each piece of metal clapboard connects the common ends of the transmission line in each cavity to each other.

Description

technical field [0001] The invention belongs to the technical field of radio communication equipment, and in particular relates to the structural design of a multi-channel power combiner / distributor. Background technique [0002] With the development of radio communication technology, power combining technology has been widely used. By combining several power amplifier units through a multiplexer / distributor, a power output of tens of kilowatts or even greater can be obtained. [0003] According to the different ways of combining / distributing, the power combiner / distributor is mainly divided into multi-channel graded synthesis and multi-channel one-time synthesis. [0004] A traditional power combiner / divider principle such as figure 1 As shown, the multi-channel hierarchical synthesis / distribution method is adopted, that is, p1 and p2, p3 and p4 are synthesized / distributed in pairs, and then a two-way synthesizer / distributor is used for synthesis / distribution, and so on t...
