The embodiment of the compatible transducer of radio frequency electric connector Waveguide coaxial is carried out as follows.
The simplification of interface.27GHz～40GHz frequency range millimeter wave product adopts the high frequency interface to mainly contain coaxial interface and Waveguide interface.In order to realize the compatibility of two kinds of interface modes, under the situation that satisfies the product instructions for use, respectively two kinds of interfaces are simplified.Coaxial interface mainly contains SMP joint form and K joint form.Can be divided into two kinds of specifications of 0.3mm, 0.38mm by the joint center bore.Can be divided into two hole flanges and two kinds of specifications of four hole flanges by joint flange dish difference.The installing hole distance of different model joint flange dish also may be different.
Coaxial interface is reduced to center bore 0.38m can join coaxial fitting 3 modes of bead 2 time, can realize that air-tightness and translation interface do not influence the function of internal circuit.The SMP joint is generally two hole flange-types, and in order to realize the exchange between K joint and SMP joint, it is two hole flange-types that joint requires, and joint installing hole distance is identical.
Waveguide interface has BJ260 and two kinds of specifications of BJ320.The millimeter wave product structure generally adopts integrated design, waveguide mouth and ring flange thereof and cavity one on the whole, indivisible.Centered by waveguide probe, waveguide mouth position has up, down, towards a left side, towards the right side, several situations forward.Therefore Waveguide interface does not have interchangeability and air-tightness.In order to improve the versatility of Waveguide interface, waveguide mouth position is unified down.When the interface of certain millimeter wave product towards requiring not simultaneously, by external custom-designed waveguide connector realize towards with the conversion of position, this work is finished by structural design teacher.Custom-designed waveguide connector also can be used as new accessory and adds to the compatible transducer of this radio frequency electric connector Waveguide coaxial, and the extended interface function improves interface adaptability.
The compatibility of interface.Because Waveguide interface and product structure are one, in order to realize the compatibility of Waveguide interface and coaxial interface, Waveguide interface must be separated separately from structure and be designed.The way that the utility model adopts is that the bead 2 of coaxial interface and interface fitting surface 14 are shared with Waveguide interface, the hour hand 8 of bead 2 is as the excitation probe of waveguide, and fitting surface 14 forms the waveguide mouth as the installed surface of self-control waveguide accessory with self-control waveguide accessory.
Selecting for use of coaxial interface connection fittings.The maximum operating frequency of the accessory bead 2 of coaxial interface selecting for use can arrive the 0.38mm specification product of 40GHz.The coaxial fitting that coaxial interface adopts also is necessary for two hole connectors of 0.38mm specification, and its aperture must be complementary with coaxial fitting installing hole 11.
The design of Waveguide interface connection fittings.The Waveguide interface accessory comprises that sleeve 5, assembling with adjustment sheet, waveguide connector 4, need design and determine size with the professional electromagnetic-field simulation of HFSS and so on.The size of BJ260 and BJ320 Waveguide interface is different with operating frequency, therefore needs the accessory of design two cover specifications, is respectively applied to this two kinds of interface shapes.
The hour hand 8 of bead 2 is directly made the waveguide excitation probe and is had shortcomings such as narrow bandwidth, matching performance difference.In order to realize the good broadband matching performance, need carry out improvement design to probe.Way is cannulated sleeve 5 of design, and is assembled on the hour hand 8, changes its diameter and length to reach the good broadband matching performance.
The shell of bead 2 is metals, touches shell formation short circuit in order to prevent sleeve 5, and because the needs of impedance matching, sleeve 5 can not be assembled to the root of hour hand 8, and L must keep at a certain distance away.The L value is determined by design of Simulation.Hour hand 8 has the long part of L not blocked by sleeve 5 and sleeve 5 constitutes the waveguide excitation probe together, how to guarantee that when assembling sleeve 5 is that L is a difficult problem to the distance of hour hand 8 roots.The way of taking is the U-shaped assembling adjustment sheet that thickness of design is L.The assembly relation of sleeve 5 and bead 2 is consulted Fig. 2.
The position of waveguide short face 15 is determined by simulation calculation in the waveguide connector 4.Waveguide connector 4 is assembled on the waveguide connector installing hole 12 of testboard carrier 1 and interface fitting surface 14 forms waveguide cavity and waveguide installed surface 16 forms waveguide mouth ring flanges, forms complete Waveguide interface, and its structure is consulted Fig. 6.
The bottom surface of testboard carrier 1 is as waveguide installed surface 16, two installing holes are set above, a hole is BJ320 waveguide installing hole 17, another hole is BJ260 waveguide installing hole 18, two waveguide installing holes are arranged on the waveguide connector 4, add the installing hole on the waveguide installed surface 16, BJ320 and BJ260 waveguide mouth all have three waveguide installing holes respectively, satisfy the mount requirement.
