Description

The waveguide duplexer of integrated waveguide isolator

Technical field

The utility model designs a kind of communication equipment element, specifically is a kind of waveguide duplexer of integrated waveguide isolator.

Background technology

In traditional design, be to separate independent the making at the waveguide duplexer and the isolator of radio-frequency front-end, work firmly links together when using at last; Isolator guarantees the normal output of signal; Yet the waveguide isolator price on the market is at 260RMB/pcs, and the loss standard of isolator own is basically all at 0.3dB, if want to accomplish the loss requirement of 0.15dB in the industry; Purchase cost almost can be at double increase, so it be fall cost the problem that must consider.

Though occurred now the design without isolator in the industry, technology itself immature limited application: not only technology is had higher requirement, and need be to system's adjustment coupling, otherwise can cause device to damage, cause system down.

In sum, the problem of prior art existence has:

When 1) waveguide duplexer and waveguide isolator shadow linked together, loss of signal was excessive.

2) the waveguide duplexer technology of inapplicable isolator is immature, and technological requirement is too high.

3) it is too high to purchase the cost of waveguide duplexer and waveguide isolator separately.

The utility model content

The technical problem that the utility model will solve be to provide a kind of simple in structure, cost is low, to the waveguide duplexer of the little integrated waveguide isolator of loss of signal.

For addressing the above problem; The utility model adopts following technical scheme; A kind of waveguide duplexer of integrated waveguide isolator comprises waveguide isolator and waveguide duplexer, and said waveguide isolator is made up of housing and waveguide isolator inner core; Be provided with input channel, output channel and three passages of load channel in the said housing; Two outputs of said waveguide duplexer are respectively equipped with a waveguide isolator, it is characterized in that integrated connection the between the cavity of the input channel A1 of said each waveguide isolator and waveguide duplexer output.

Preferably, the integrated connection between the cavity of waveguide isolator load channel A2 and waveguide duplexer.

Preferably, waveguide isolator load channel A2 is provided with the load of wedge shape tinfoil paper; Load of wedge shape tinfoil paper and passage A2 are bonding.

Preferably, the waveguide isolator inner core is positioned at three passages of waveguide isolator housing and intersects the center, and the lower counterbore through cover plate and cavity bottom and cover board hole opposite position is fixed on the housing.

Preferably, the waveguide isolator inner core is made up of cover plate, support column, three cobalt magnets and ferrite; 2 three cobalt magnets in the upper end of said waveguide isolator inner core and a support column are nested in the cover plate; 2 ferrites in lower end are nested in the center through hole in the support column; Support column embeds in the lower counterbore of cavity bottom.

Preferably, the waveguide duplexer of integrated waveguide isolator surface parcel one deck Al-alloy casing.The beneficial effect of the utility model:

1, after the integrated connection, structure is more simple;

2, the waveguide duplexer adopts integrated the connection with waveguide isolator, has reduced the influence to signal of external circuit and external environment, and loss is dropped to 0.2dB to 0.15dB from 0.3dB;

3, integrated connection back materials minimizing has reduced purchase cost.
