Embodiment
Below in conjunction with accompanying drawing 1-3, application scheme is further described：
A kind of feed waveguide integration stairstep signal phase shifter, including main body 1 and the corrugated horn positioned at the front end of main body 1 are presented
Source 2, the rear end of main body 1 outside are provided with circuit board installation position 11, and the connector installation communicated with the circuit board installation position 11
Position 12, the main body 1 have a waveguide cavity 3 and step phase shift device 4 successively from front to back, and the step phase shift device 4 is in the form of sheets and longitudinal direction
Symmetrical to separate waveguide cavity 3, front side is stepped is placed with five ladder blocks 4a, 4b, 4c, 4d and 4e for it, specifically, each rank
The ladder of terraced block is of different sizes H1, H2, H3, H4 and H5, and the different sizes are carried out according to the requirement of the affiliated wave band of product
Adjustment, the corrugation loudspeaker feed source 2, waveguide cavity 3 and step phase shift device 4 are integrally formed；Specifically, the corrugation loudspeaker feed source 2
The transition 21 being connected including the waveguide mouth 31 with waveguide cavity 3, and some annular walls 22 being coaxially disposed, two-by-two annular wall 22
Between formed annular groove 23.From the inside to the outside, the opening's edge of the annular wall 22 is incremented by successively with respect to the axial distance of waveguide mouth 31.Satellite
Descending circularly polarized signal is after the amplification and collection of satellite antenna reach the filtration fraction clutter of corrugation loudspeaker feed source 2 from waveguide
Mouth 31 is transferred into, and the interception that the progress signal wavelength of step phase shift device 4 and phase are entered then along waveguide mouth 31 is changed, and is passed through
Circularly polarized signal is changed into linear polarization signal after conversion, and the signal so after accurate transformation phase shift is easier and vertical, water
Flush and receive probe antenna matching, amplify signal down below more stable, performance is more preferable.
Upper table shows that gain inequality corresponds to separation number table, by experimental data it can be seen that the utility model product every
There is preferable performance from degree.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximation or the technology deduction made based on this, replacement, improvement etc., it is regarded as the protection domain of this patent.
