Description
Technical field
The present invention relates to one kind to be mainly used in the extensive active device high efficiency power combing amplification of millimeter wave high band
Power distributing network in device.
Background technology
Millimeter wave high power amplifier is millimetre-wave attenuator, radar, observing and controlling, the critical component of navigation system emitter.
In order to realize the performances such as the bigger operating radius of system, stronger antijamming capability, more preferable communication quality, it is necessary to possess enough
Big power output.And due to all many limitations such as Semiconductor Physics characteristic and processing technology, also it is difficult to produce at present
Go out high-power, low noise, the millimeter wave solid-state amplifier of high performance-price ratio, especially in millimeter wave high band, therefore power combing
As the only way of premium properties solid-state system is realized, it is divided into chip-scale, circuit-level, space level, and various power combing skills
The core of art is all power distributing network.Chip scale power synthesis is on same semiconductor chip, by multiple power tube pipes
Core is connected in parallel in the certain area less than wavelength, is connected using matching network, realizes its power superposition output Gao Gong
Rate.A definite limitation be present in this synthesis mode：With the rise of working frequency, operation wavelength shortens, available for power combing
Area size reduces, and the manufacture difficulty of biasing and match circuit is accordingly increased, and the number of synthesis chip is also restricted therewith, from
And constrain the power output of whole synthesis system.Simultaneously because the spacing of chip chamber narrows so that heat dissipation problem is more prominent.
Therefore chip power synthesis can not meet the requirement of big power output.Circuit-level power combing can by the difference of circuit form
It is divided into the synthesis of disresonance type circuit and resonant circuit synthesis.The shortcomings that some are intrinsic, disresonance type circuit be present in two ways
Synthesizing with the increase of combining amplifier quantity, transmission loss is increasing, causes combined coefficient relatively low, when frequency raises, property
It can deteriorate more serious；Resonant circuit synthetic work frequency band is narrow, and device count is limited by cavity modes；As synthesizer increases
More, frequency rise, cavity space can be less and less, and pattern caused by various noncoherent boundaries will become to become increasingly complex, sternly
Ghost image rings stability, combined coefficient and the power output of synthesizer work.Space power synthesis passes through the work(active device
Rate exports again coupled to large aperture leading wave beam.Extensive device can be achieved in single-stage to integrate, and be lost with device count almost
It is unrelated.Again because energy is to disperse to be coupling in space combination, ohmic loss very little.But the distribution of current space power synthesis
There is wave beam conversion twice in network, spherical wave turns quasi-plane wave and quasi-plane wave phase inversion position profile, and multiple conversions can all have damage
Consumption；Mostly realized in free space, electromagnetic-wave leakage is serious, is unfavorable for improving efficiency and electromagnetic Compatibility Design；Each point
Module relative positioning structure is inadequate, if the deviation from design attitude, wave beam relative phase relation will be caused to change, system effectiveness can show
Writing reduces.
In summary, prior art is also difficult to that millimeter wave high band is extensive, high efficiency, the work(of excellent electromagnetic shielding
Rate is distributed.
The content of the invention
The present invention is in place of above-mentioned the shortcomings of the prior art, there is provided one kind can the active device of high efficiency large-scale integrated
Part, capability of electromagnetic shielding are excellent, the quasi-optical power distributing network of metal enclosed chamber suitable for millimeter wave high band, to break through millimeter

The wide input plane 10 of waveguide battle array phase shift lens 2, output plane 11 are closely connected with input loudspeaker 19, output loudspeaker 12 respectively；Penetrate
The input waveguide mouth 8 that frequency signal is provided with one-level input step conversion 9 from inwall inputs, and is converted through metal enclosed input loudspeaker 19
The amplitude wave beam such as approximation is formed at the input plane 10 of waveguide battle array phase shift lens 2 that broadens, is shone by relevant quasi-plane wave of this wave beam
The waveguide battle array phase shift lens 2 that broaden are mapped to, the multiple amplitudes of generation are approximately the same at output plane 11, the distribution of phase cycling rule
Relevant partial wave beam, be concerned with partial wave beam diffraction, interference in metal enclosed diffraction chamber 1, in the bore of output loudspeaker 12 of period profile
Place's 18 amplitudes of formation are approximately the same, phase is pressed the focus point of periodic law change, and received by 18 output loudspeaker 12, then passes through
After one-level output step conversion 15, exported by 18 standard output waveguide mouths 7, real-time performance is distributed by one-level so as to complete
1 point of 18 tunnel power distribution.
The present invention has the advantages that compared to prior art.
The present invention realizes 1 point of 18 tunnel by one-level power distribution, and realizes 1 point of 16 tunnel distribution and be required for 4 grades 1 point of cascade
2 circuit powers distribute network, and the reduction of power distribution series reduces circuit loss, improves power distribution efficiency.The present invention
Based on holography principle：By multiple coherent source wave beams and a branch of reference beam coherent plane wave in space interference, utilization space
The negative writing the formation of interference fringes hologram of ad-hoc location；, can be complete when irradiating hologram with same reference beam
Recover the amplitude and phase of each coherent source wave beam.In the present invention, the wave beam converted using inputting loudspeaker after 19 is used as reference light
Beam coherent plane wave is irradiated to the input plane 10 of the waveguide battle array phase shift lens 2 that broaden as hologram, in output plane 11
Later by interference, diffraction, the approximately equalised relevant partial wave beam of multiple amplitudes can be produced, to complete power distribution.Using the original
