As shown in Figures 1 and 3, the box intracavity of housing 11 is provided with 90, three groups of one group of main 80, five groups of transition micro-strip plate of power amplifier to body
50, three groups of isolators of 60, one group of 50w power amplifier of power supply board, 110, two groups of 150w power amplifiers 70 of 100, three groups of electric capacity with
And allotter micro-strip plate 120, waveguide combiner 20, bonder 30 and wave filter 40.As shown in figure 1, housing 11 side is provided with
Adapter and xch adapter.The affixed panel of one terminal bolt 15 of the length direction of housing 11, as shown in figure 4, pacify on panel 15
Equipped with two semiconductor lamps, a handle and three key switches.Then it is provided with and radiating fin 14 meta at the housing 11 box back of the body
Put the monitoring of emission 130 of avoidance.It is provided with through wires hole, to be located at each portion at housing 11 box chamber and the box back of the body at the cassette bottom of housing 11
Part is electrically connected to each other.Whole device is all using standardized designs.
During concrete operations, the integral structure that housing 11 is made for aluminium alloy, upper cover plate 12, lower cover 13 adopt duralumin to close
Golden material, three is all processed using electric conductive oxidation.Due to main power amplifier 80, transition micro-strip plate 90, power supply board 60,50w work(
Rate amplifier 50, isolator 100, electric capacity 110,150w power amplifier 70 and allotter micro-strip plate 120 caloric value are big, for this
Housing 11 back side of all of above electrical part contact surface is designed with radiating fin 14 as shown in Figure 2.Radiating is concentrated by setting
Region simultaneously increases radiator structure, and then solves the problems, such as the high efficiency and heat radiation of heating element well.Install concentrating heat dissipation region
After the completion of, for the components and parts easily producing electromagnetic interference problem to each other, such as power supply board 60,50w power amplifier 50 and
Between 150w power amplifier 70, shielded partitions 16 are set, thus reaching the shield effectiveness between adjacent components and parts.In addition, mistake
Cross micro-strip plate 90, power supply board 60,50w power amplifier 50, isolator 100,150w power amplifier 70 and allotter micro-strip plate
All being connected using weld tabs between 120, having abandoned the attachment structure of cable, thus greatly improving the compactedness of internal structure.
The lettering of panel 15, paint and partly often operating parts is easily destroyed, therefore housing 11 adopts detachable fixed form with panel 15,
As waited demountable structure using screw is affixed, in order to the maintenance of panel 15.
Radio frequency output in view of traditional transmitter generally adopts cable connection, and often electric signal leakage is larger.Waveguide is closed
Grow up to be a useful person 20, bonder 30, wave filter 40 composition radio-frequency plumbing assembly, employ the modularity as shown in Fig. 1, Fig. 3 and Fig. 5 and set
Meter, thus excessive cable connection before decreasing, not only assembles more convenient, also plays simultaneously and avoid microwave signal
The effect revealed, achieves many things at one stroke.Each face matching part of radio-frequency plumbing assembly adopts standardization flange to connect, and also will above-mentioned join
After conjunction face carries out ring flange cooperation, fixing using four screws, later maintenance of being more convenient for.Form method in radio-frequency plumbing assembly
While blue cooperation, around electrical connecting passage to each other, on flange face, ring sets shield gasket circle, thus lift each face joining
Close the effectiveness at position, finally further lift the sealing ability of microwave signal.
