Manufacture field at microwave telecommunication devices all to know, the waveguide duplexer of the same band has numerous frequency sub-band, several at least, up to a hundred at most, and the passband width of frequency sub-band have wide, have narrow, what what the belt distance of duplexer low-and high-frequency passband had far had is near, so, just requires that the adjustable extent of waveguide duplexer very extensively will could cover numerous frequency sub-band.If the adjustable extent of waveguide duplexer is little, just needs multiple duplexer to cover all frequency sub-band, like this, will production cost be increased, reduce production efficiency.Wherein, the adjustable extent size of waveguide duplexer depends primarily on antenna opening coupling mechanism.
Traditional antenna port of waveguide duplexer coupling mechanism comprises plate-like body, the one side of plate-like body has high frequency first resonant cavity and low frequency first resonant cavity, all has harmonic oscillator in high frequency first resonant cavity and low frequency first resonant cavity.The one side that described plate-like body has high frequency first resonant cavity and low frequency first resonant cavity has cover plate, and all there is screw the cover plate place corresponding with the harmonic oscillator in high frequency first resonant cavity and this both sides, place, all have high-frequency tuning screw in screw.All there is screw the cover plate place corresponding with the harmonic oscillator in low frequency first resonant cavity and this both sides, place, all have low frequency tuning screw in screw.Antenna opening coupling mechanism is had between described high frequency first resonant cavity and low frequency first resonant cavity, as shown in Figure 1, this coupling mechanism is an external metalwork, utilizes external metalwork and empty waveguide to match to realize being coupled of waveguide duplexer common waveguide mouth and antenna opening.Although adopt external metalwork can realize being coupled of waveguide duplexer common waveguide mouth and antenna opening, because external metalwork is a part independent of duplexer body, in assembling process, there is certain tolerance, make electrical property consistency poor.Again due to the part that external metalwork is independent of duplexer body, in process of production, step is many, and not only production efficiency is not high, and can increase production cost.On the other hand, owing to utilizing external metalwork and empty waveguide to match to realize being coupled of waveguide duplexer common waveguide mouth and antenna opening, make the useful space taking waveguide duplexer many, the bandwidth of coupling is narrower, only have 800MHz.
Utility model content
Problem to be solved in the utility model is to provide a kind of antenna port of waveguide duplexer coupling mechanism.Adopt this coupling mechanism, not only can enhance productivity, reduce production cost, and the bandwidth of coupling can be increased.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Antenna port of waveguide duplexer coupling mechanism of the present utility model comprises plate-like body, the one side of plate-like body has high frequency first resonant cavity and low frequency first resonant cavity, all has harmonic oscillator in high frequency first resonant cavity and low frequency first resonant cavity.The one side that described plate-like body has high frequency first resonant cavity and low frequency first resonant cavity has cover plate, and there is screw at the cover plate place corresponding with the harmonic oscillator in high frequency first resonant cavity, all has high-frequency tuning screw in screw.There is screw at the cover plate place corresponding with the harmonic oscillator in low frequency first resonant cavity, all has low frequency tuning screw in screw.Antenna opening coupling mechanism is had between described high frequency first resonant cavity and low frequency first resonant cavity.Be characterized in that described antenna opening coupling mechanism to comprise between high frequency first resonant cavity and low frequency first resonant cavity the common waveguide mouth at the bottom of chamber, there is screw at the cover plate place corresponding with common waveguide mouth, is furnished with low-and high-frequency and shares coupling tuning screw in screw.High frequency first resonant cavity and low-and high-frequency shares between coupling tuning screw, low-and high-frequency shares coupling tuning screw and between low frequency first resonant cavity and high frequency waveguide mouth, low frequency waveguide mouth corresponding position cover plate on be all processed with screw, all have coupling tuning screw in screw.
Wherein said harmonic oscillator is metal harmonic oscillator, forms as one at the bottom of the bottom of this metal harmonic oscillator and the chamber of corresponding resonant cavity.
Such scheme is taked to have the following advantages:
As can be seen from the above scheme, the common waveguide mouth at the bottom of chamber is comprised between high frequency first resonant cavity and low frequency first resonant cavity due to described antenna opening coupling mechanism, there is screw at the cover plate place corresponding with common waveguide mouth, is furnished with low-and high-frequency and shares coupling tuning screw in screw.Avoid the performance index difference and destabilizing factor that use the tolerance brought of external metalwork and build-up tolerance to cause.Add the utility model need not empty waveguide mate, direct connection low-and high-frequency two ends passage, facilitates the arrangement of the total of waveguide duplexer, is fully used in the space of duplexer, not only make duplexer performance index consistency good, and volume reduce greatly.Again owing to not using external metalwork, in waveguide duplexer manufacturing process, decrease a procedure, not only increase production efficiency, and reduce production cost.In addition, owing to external metalwork and empty waveguide need not match and realize being coupled of waveguide duplexer common waveguide mouth and antenna opening, make the useful space taking waveguide duplexer few, the broader bandwidth of coupling, up to 2000MHz.
