Description
Technical field
The utility model relates to switching amplifier technical fields, and in particular to a kind of new type multipath switch amplifier module.
Background technique
Variable connector amplifier module is that multichannel input signal is sent to switch, and power splitter is then recycled to be divided into multichannel letter
Number, and amplify filtering and form multiple signals.The multiple signals of existing variable connector amplifier module output there are output phase and
Power is inconsistent, and clutter is big, the problem of isolation difference between multipath output signals.
Summary of the invention
Goal of the invention: the utility model aim be in view of the deficiencies of the prior art, provide a kind of phase of output signal and
Power consistency is high, clutter is small, isolation is high, switch response time fast new type multipath switchs amplifier module.
Technical solution: new type multipath described in the utility model switchs amplifier module, including several signal input ports, the
One power-devided circuit, switching circuit, the second power-devided circuit and filtering and amplifying circuit, every road input signal is through the first power-devided circuit point 4
Road output, 4 tunnel output signals connect with 4 switches of switching circuit respectively and export 1 road signal, then through the second power-devided circuit point
It is exported after filtering and amplifying circuit amplification filtering after two-way；The filtering and amplifying circuit includes sequentially connected amplifier and filtering
Device.
Above-mentioned technical proposal is further improved, first power-devided circuit includes second level power splitter, and input signal is passed through
First order power splitter divides two-way to export, then respectively through the output of 2 second level power splitters point, four tunnels.
Further, the filtering and amplifying circuit further includes attenuator, constitutes sequentially connected amplifier, attenuator, puts
Big device and filter.
Further, including 3 signal input ports, switching circuit use 4 single-pole three-throw switches, every road input signal
It is connect respectively with 4 single-pole three-throw switches through the output of 4 tunnels of the first power-devided circuit point, exports 1 road signal through single-pole three-throw switch.
It further, further include 2 road fault detection circuits, the output signal of filter 1 and filter 8 is through fault detection electricity
It is exported behind road.
The utility model has the advantages that (1) the utility model provides multiple signals input, there is a 8 tunnel output signals, the power of output signal and
Phase equalization is high, clutter is small, realizes isolation >=45dB between Lu Yulu, isolation > 80dB of each switch, switch
Influence time is fast；Structurally reasonable, small in size, reliable performance is suitble to extensive production application.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment

Embodiment 1: a kind of new type multipath switch amplifier module, as shown in Figure 1, including 3 signal input ports, the first function
Parallel circuit, switching circuit, the second power-devided circuit, filtering and amplifying circuit and fault detection circuit；Every road input signal is through the first function
The output of 4 tunnels of parallel circuit point, 4 tunnel output signals connect with 4 switches of switching circuit respectively and export 1 road signal, then through second
Power-devided circuit exports after filtering and amplifying circuit amplification filtering after dividing two-way；The filtering and amplifying circuit includes sequentially connected puts
Big device, attenuator, amplifier and filter.
First power-devided circuit includes 3 power splitters, and the first power-devided circuit uses second level power splitter, every road input signal
Two-way is divided to export by first order power splitter, then respectively through the output of 2 second level power splitters point, four tunnels.
The switching circuit includes 4 single-pole three-throw switches, and the 4 road signals exported through second level power splitter pass through hilted broadsword list
Switch is connect with 4 single-pole three-throw switches respectively, and 1 road signal is exported after single-pole three-throw switch.
Second power-devided circuit includes 1 power splitter, and the 1 road signal exported through single-pole three-throw switch is divided to two through power splitter
Road is exported respectively to filtering and amplifying circuit.The output signal of filter 1 and filter 8 exports after fault detection circuit detects.
The electrical characteristic parameter of variable connector amplifier module described in the utility model is as shown in the table:
Table 1
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
