A BJ-40 standard waveguide port (2) of a BJ-40 rectangular waveguide cavity (1) is connected with a rectangular flange disc (3). The center of the closed end of the BJ-40 rectangular waveguide cavity (1) is provided with a first tuning screw (4) which is matched with a second tuning screw (5) of a matching step (6). One side wall of the BJ-40 rectangular waveguide cavity (1) is fixedly connected with an SMA connector (7). A probe (8) of the SMA connector (7) stretches into and is welded with an axle hole of a coupling column (9). The stretching depth of the probe (8) is 4.5 mm. The radius of the coupling column (9) is 3.1 mm, the length of the coupling column is 8 mm, and the coupling column is provided with the axle hole in the center. The second tuning screw (5) is axially and directly facing to the axis of the coupling column (9).
Description
technical field:
The present invention is relevant with the Waveguide coaxial conversion head of microwave communication, satellite communication, Aero-Space electronic equipment.
background technology:
Waveguide coaxial conversion head is parts crucial in communication system, for the signal of assigned frequency, in waveguide with coaxially, transmits preferably.
Waveguide coaxial conversion head bandwidth is in the market narrower, and form is comparatively single, is mainly step conversion form and probe form, and bandwidth is narrower, and performance is not fine.The Waveguide coaxial conversion head of step conversion form and probe form is due to coupling and coupled problem, and bandwidth all can not be accomplished very wide, cannot reach waveguide full frequency band.
summary of the invention:
The object of this invention is to provide a kind of bandwidth, standing wave is little, is easy to manufacture, failure rate is low, safe and reliable Waveguide coaxial conversion head.
The present invention is achieved in that
BJ-40 standard waveguide the mouth 2 of BJ-40 rectangular waveguide cavity 1 is connected with rectangular flange dish 3, the blind end center of BJ-40 rectangular waveguide cavity 1 has the first tuning screw 4 to coordinate with the second tune screw 5 of coupling step 6, one sidewall of the BJ-40 rectangular waveguide cavity 1 SMA connector 7 that is connected, the probe 8 of SMA connector 7 stretches in the axis hole of coupling column 9 and its welding, the degree of depth that stretches into of probe 8 is 4.5mm, the radius of coupling column 9 is 3.1mm, length is 8mm, there is axis hole centre, the axial just axle center to coupling column 9 of second tune screw 5.
SMA-KFD22 that described SMA connector is Hua Da.BJ-40 standard waveguide mouth 2:58.17 × 29.08 × 55mm.Coupling step 6:20 × 9 × 6.1mm.
Operating frequency range of the present invention is 3.4～4.75GHz; Standing wave≤1.3.Bandwidth approaches BJ-40 waveguide full frequency band and standing wave requires very strict.Final the be coupled form of additional coupling step of cylinder of using has realized high technical indicator like this.The present invention has used coupling step and tuning screw to strengthen coupling signal is finely transmitted to coaxial matchingly by waveguide.Strengthened coupling with cylinder coupling, in wide frequency band, also had good standing wave, have be with wide, standing wave good, be easy to manufacture, failure rate is low, safe and reliable, index good, stability is high, meet the advantages such as ROHS standard.Realized and allowed the signal of BJ-40 waveguide full frequency band transmit well in waveguide with coaxially, standing wave is all below 1.3.
