Maximum characteristics of the present utility model are: the coupling amount difference between two outputs, can regulate the energy value that is coupled between the two-port according to the engineering actual demand; Phase difference between two outputs is far smaller than the phase difference that the H-ground roll that generally adopts is led the crack electric bridge, and promptly the phase difference between output port A, the output port B is far smaller than the phase difference that the H-ground roll that generally adopts is led the crack electric bridge.Because the H-ground roll is led locational notable difference between two output ports of crack electric bridge and the input, the phase difference of two output in whole working band all about 90 degree.In waveguide power divider, we usually need between two outputs of power splitter phase difference in whole working band less than certain value, such as 3 degree or 5 degree.In order to satisfy this equiphase requirement, the most frequently used method is two outputs connection waveguide phase compensating circuits of leading the crack electric bridge at the H-ground roll.There is work zone width in this compensating circuit and increases the problem of power splitter volume.Particularly when adopting multistage H-ground roll to lead crack electric bridge formation multichannel power division network, the problems referred to above are more serious.Power splitter of the present utility model makes the relative port of input become isolation end, makes the relative port of input port become isolated port A, and output port A, output port B are good with respect to the input port symmetry.Particularly when we with whole power splitter be designed to respect to before and after the input port to about axis fully during symmetrical structure, power and the phase place of output port A, output port B are identical, but owing to regulate the coupling amount of two output ports, coupling body in the coupling regime is the boundary with the coupling regime front and back to axis, before and after being positioned to the coupling body in axis left side be positioned at before and after coupling body to the axis right side constitute asymmetrical two coupling bodies, cause as long as promptly satisfy the not of uniform size of coupling body, thereby can cause two output ports to have certain phase difference.But this difference is smaller, about 5 degree.This is acceptable in power splitter.Therefore, the coupling amount that the six port H ground rolls that the utility model provides are led output port A, the output port B of unequal power distributor can be ratio not arbitrarily, phase difference also within the acceptable range, have between output port A, the output port B 15dB even 20dB with good isolation, can be used as single power splitter and use, particularly can be connected in series formation multichannel power division network and use.Device has clear superiority aspect performance, bandwidth of operation and the volume.
Operation principle of the present utility model can be summarized as follows under the situation of symmetric form rectangular coupled cavity and rectangle input and output waveguide.The cross section is that the input port of rectangle has mainly encouraged two waveguide mode of operations, i.e. TE10 pattern and TE30 pattern in the coupling cavity of cuboid structure.The ripple of these two patterns all will be propagated along the input waveguide axis direction.Because the guide wavelength difference of these two patterns, at the other end of coupling cavity, the power that output port A and output port B and isolated port A are coupled out from coupling cavity be the power that from the ripple of two mode of operation TE10 patterns and TE30 pattern, is coupled out respectively and.By width and the length of choosing coupling cavity, and size and the position of input port, isolated port B, isolated port C and isolated port A, output port A, output port B, the power phases that isolated port A is coupled out from two mode of operations respectively differs 180 degree, cancel out each other, the power phases that output port A and output port B are coupled out from two mode of operations respectively differs the integral multiple of 0 degree or 360 degree, mutual superposition.At this moment, all energy are all exported from output port A and output port B coupling basically, and do not export from isolated port A.The position of size, position and coupling body by changing output port A and output port B and the coupling amount that shape can be regulated an output port.Because two mode of operation TE10 patterns of input port excitation and TE30 satisfy naturally at isolated port B, isolated port C place and anti-phasely disappear mutually, the power that is coupled out from isolated port B, isolated port C is all very little, thereby isolated port B, isolated port C are used as isolation end.In order further to widen the bandwidth of operation of device, the shape of coupling cavity, particularly width can suitably change to axis along the front and back of input port, can also increase groove A or metal boss (metal column) in coupling cavity.Each input/output terminal can increase one or more levels matching section.Coupling cavity and input port, isolated port B, isolated port C and isolated port A, output port A, output port B are shaped as other when distortion, and the operation principle that this six port H ground roll is led unequal power distributor also can be set forth and understands according to above content.
The power output of two output ports of the present utility model can be carried out not five equilibrium power division, and its phase difference also in power division device acceptable scope, is particularly suitable for serial connection and constitutes the multichannel power division network.That the utility model also has is simple in structure, volume is little, the characteristics that difficulty of processing is low.The utility model can be widely used in that antenna array, phased array radar and power are synthetic, missile guidance, military affairs and civil area such as communicate by letter.
