Description
Technical field
The present invention relates to a kind of multiplexer.Specifically, it is that can cover the wave filter of multiple working frequency range, it is adaptable to channel radio
On the communication equipment for believing base station.
Background technology
With the development of the communication technology, more and more wider is required to the working frequency range of multiplexer.And as multiplexer works frequently
Broadening, requirement to the antenna coupling mechanism of the multiplexer of the multiple working frequency range also more and more higher of section.
At present, on multiplexer the inductive coupled mechanism and dumbbell shaped electric capacity of the main useful copper wire welding of antenna coupling mechanism
Coupling mechanism.The coupling mechanism of copper wire welding includes common resonant chamber and harmonic oscillator, and the harmonic oscillator of common resonant intracavitary is led to each
Harmonic oscillator in first resonator in road is respectively arranged with copper wire, and the two ends of the copper wire are respectively welded in corresponding harmonic oscillator.
The coupling mechanism welded using this copper wire, the interactional method between high frequency and low frequency that eliminates be change copper wire length or
Curved shape, due to the uncertainty of the curved shape of copper wire, it is difficult to ensure that the performance of each multiplexer is the same so that each is more
The uniformity of work device is poor, it is difficult to produced in batches.Again because copper wire needs welding, the size of solder joint is difficult to keep the same,
So, the uniformity of each multiplexer can also be influenceed so that batch production is relatively difficult.
Dumbbell shaped Capacitance Coupled mechanism is included between two harmonic oscillators being arranged in public resonator, described two harmonic oscillators
Coupling bar is provided with, there is coupling disc at the two ends of coupling bar.For the wider multiplexer of frequency band, it is desirable to coupling disc and resonance
Spacing between son is the smaller the better.Due to the spacing very little between coupling disc and harmonic oscillator, and naked measure, easily sparking so that
Power capacity is small, therefore, can be used only on low-power communication equipment, it is impossible to on high-power communication equipment, the scope of application by
To limitation.
The content of the invention
The problem to be solved in the present invention is to provide a kind of broadband multiplexer.This broadband multiplexer, uniformity is good, can batch
Production, the scope of application is unrestricted.
The invention solves the problems that above mentioned problem by being realized with technical scheme：
The broadband multiplexer of the present invention, including body and cover plate, the body are tabular.Body be connected with cover plate one
Face, which has in the middle of in the flat hole similar to body edge shape, flat hole, median septum, and the both sides of the median septum have at least
One side dividing plate, between the median septum and side dividing plate and outermost side dividing plate is parallel between adjacent crater wall.In described
Crater wall of the same vertical edge of dividing plate and side dividing plate with adjacent side forms as one, another same vertical edge of median septum and side dividing plate with
Leave the spacing for forming public coupler between the crater wall of adjacent side, and between median septum and adjacent side crater wall be smaller than side every
Spacing between plate and adjacent side crater wall.Between the median septum and side dividing plate, between sides adjacent dividing plate and outermost side dividing plate with it is adjacent
Have in passage between the crater wall of side for by the channel partition, into the midfeather of at least two resonators, having in the middle of midfeather to be used for
Being formed in the opening of coupling aperture, the resonator has the second harmonic oscillator.There is antenna to couple in spacing between median septum and crater wall
Mechanism, antenna coupling mouth mechanism includes two the first harmonic oscillators, first harmonic oscillator and the second resonance in respective channel
There is tuning screw on cover plate on cover plate between son, between each passage resonator.Line between described two first harmonic oscillators with
The crater wall of adjacent side is parallel, has take-off lever with having in line interphase pair and that neighbouring crater wall in antenna opening, antenna opening.Its
Feature is that the take-off lever inner end has coupling bar, and the coupling bar is vertical with the plate face of median septum, with output in the middle of the coupling bar
Bar inner end links together.There are transverse holes in one first harmonic oscillator, coupling bar one end is penetrated in transverse holes in insulation shape,
There is coupling disc on coupling bar at the coupling bar other end and neighbouring that first harmonic oscillator with transverse holes, it is neighbouring with horizontal stroke
Insulating disc is connected between the coupling disc and harmonic oscillator at that harmonic oscillator in hole.
Such scheme is taken, with advantages below：
As can be seen from the above scheme, because there is coupling bar the take-off lever inner end, the plate face of the coupling bar and median septum
Vertically, linked together in the middle of the coupling bar with take-off lever inner end.There are transverse holes, coupling bar in one first harmonic oscillator
One end is penetrated on the coupling bar at transverse holes, the coupling bar other end and neighbouring that harmonic oscillator with transverse holes in insulation shape
There is coupling disc, insulating disc is connected between the coupling disc and harmonic oscillator at neighbouring that harmonic oscillator with transverse holes.With background technology
The coupling mechanism of middle use copper wire welding is compared, and without copper wire, can be eliminated influencing each other between high frequency and low frequency, be can guarantee that each
The performance of multiplexer is the same so that the uniformity of each multiplexer is good, can be produced in batches.With the dumbbell shaped in background technology
Capacitance Coupled mechanism is compared, and the pitch requirements between coupling disc and corresponding harmonic oscillator to coupling bar two ends are not high, can avoid sparking
Situation occurs, and power capacity is big, can not only be with low-power communication equipment, moreover it is possible to on high-power communication equipment, be applicable
Scope is unrestricted.
