The upper surface of dielectric-slab, the lower surface of dielectric-slab are overlapped with the lower surface of air cartridge, and output port is located at the right side of air cartridge.
During work, the Ku waveband radio frequencies signal of input port input transmits downwards by step waveguide, and coaxial probe is from vertical
Step waveguide directly is inserted into the broadside of step waveguide, and coaxial probe is located at range step waveguide short face quarter-wave
Position.Because after step waveguide terminal short circuit, forming standing wave in step waveguide, distance is half wavelength between node,
The quarter-wave position in the range step waveguide short face anti-node location most strong for electric field, the efficiency of coaxial probe coupling is most
It is high.Ku band signals are coupled to through step waveguide on coaxial probe, are then transferred on microstrip line by glass insulator, finally
It is output to output port.
The step waveguide of the present invention realizes impedance transformation in waveguide cavity by way of increasing ladder, by higher wave
It leads impedance and transforms to relatively low probe and micro-strip impedance, effectively extend coupling bandwidth.Microwave/millimeter wave hydrid integrated circuit
In commonly used microwave monolithic microwave integrated circuit be usually bare chip, these bare chips using microstrip line realize signal pass
It is defeated, it is therefore necessary to which that the microstrip line part sealing comprising bare chip just can guarantee to the long-time service longevity of bare chip using special process
Life, the sealing problem of waveguide cavity and microstrip line can be well solved using the Waveguide-microbelt converter of coaxial probe transition type.
Meanwhile the Ku band broadband Waveguide-microbelts converter of coaxial probe transition type of the invention also have size it is small, it is simple in structure, hold
Easy processing, high reliability.
