Great inconvenience is carried out.
How to reduce the volume of electric bridge waveguide and high pass filter, just become an important research topic；But it is general
In the case of, it is desirable in the case where using effect is not affected, volume is carried out to waveguide or high pass filter individually, it is various to adapt to
Narrow and small placement space is extremely difficult.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of waveguide bridge with high pass filter function,
Waveguide broadside is gradually narrowed by first wave guide changeover portion, the cut-off characteristicses of low frequency signal are reached using the waveguide after narrowing
The High frequency filter of input signal is acted on, then input signal is divided into two by waveguide coupling slot, realize the work(of waveguide bridge
Energy；It is without being cascaded single waveguide bridge and high frequency filter again, small volume, lightweight, easy to process.
The purpose of the present invention is achieved through the following technical solutions：A kind of waveguide bridge with high pass filter function,
Including the waveguide coupling slot of waveguide and lower waveguide in upper waveguide, lower waveguide and connection, one end of the upper waveguide is provided with ripple
Input port is led, the first wave guide changeover portion that waveguide broadside is gradually narrowed between waveguide input port and upper waveguide, is provided with, it is described

Isolated port.
Further, the first described output waveguide mouth and the second output waveguide mouth are symmetrical with regard to waveguide coupling slot.
Further, it is provided with the waveguide broadside that will be narrowed between described upper waveguide and first wave guide delivery outlet gradually to become
Wide second waveguide changeover portion.
Further, the waveguide broadside that will be narrowed is additionally provided with gradually between described lower waveguide and second waveguide delivery outlet
The 3rd waveguide transition section for broadening.
Further, described waveguide input port, first wave guide delivery outlet and second waveguide delivery outlet are standard waveguide
Mouthful.
The invention has the beneficial effects as follows：（1）Waveguide broadside is gradually narrowed by first wave guide changeover portion, after narrowing
Waveguide the cut-off characteristicses of low frequency signal are reached the High frequency filter of input signal are acted on, then by waveguide coupling slot being input into
Signal is divided into two, and realizes the function of waveguide bridge, without again single waveguide bridge and high frequency filter are cascaded, body
Product is little, lightweight, easy to process；（2）The waveguide broadside that will be narrowed is provided between upper waveguide and first wave guide delivery outlet gradually
The second waveguide changeover portion for broadening, is additionally provided with the waveguide broadside that will be narrowed between lower waveguide and second waveguide delivery outlet and gradually becomes
The 3rd wide waveguide transition section, to realize being matched with the first wave guide delivery outlet and second waveguide delivery outlet of standard, it is ensured that
Excellent standing-wave ratio is obtained in passband.
