Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of K-band satellite reception outdoor unit, as shown in Figure 1, include cavity 1, circuit board 2 and feed 3, circuit board 2 is arranged in cavity 1, chamber, one end wall of cavity 1 is provided with signal output connector 4, other end chamber wall is provided with feed Connection Block 5, as shown in Figure 2, feed Connection Block 5 is provided with probe cavity volume 6 recessed bottom cavity 1, probe 7 is provided with in probe cavity volume 6, as shown in Figure 3, probe 7 is straight rod-shaped, probe 7 one end is free end, the other end to be vertically fixed on bottom cavity 1 and to extend up in cavity 1 and welds together with the distributing point of circuit board 2, as shown in Figure 4 and Figure 5, feed 3 is the cylindrical cavity of one end with conical head 8, the front end of conical head 8 is provided with adpting flange 9, feed 3 to be connected on feed Connection Block 5 by adpting flange 9 thus to make the probe cavity volume 6 on feed 3 internal cavities and feed Connection Block 5 through.
During concrete enforcement, cavity 1 takes disposable die casting to make during fabrication, on the sidewall of one end, preserved signal out splice going splice 4 exports, the feed Connection Block 5 of the other end and all disposable die casting of the probe cavity volume 6 of its inside form, probe 7 is vertically through bottom cavity 1, and it is inner that cavity 1 is stayed in its upper end, and lower end is stayed in probe cavity volume 6, bottom probe 7 and cavity 1, plastics spacer 10 is set by place, freely can be changed the direction of probe 7 by the isolation of plastics spacer 10 as required.Circuit board 2 lies in bottom cavity 1, weld with the pad in circuit board 2 front after what probe 7 upper end was given prominence to partially pass through circuit board 2, signal output part and the signal output connector 4 of circuit board 2 other end weld together, and signal output connector 4 adopts F head and external reception equipment connection.Signal energy loss is caused in order to prevent useful signal radiation, prevent extraneous signal from disturbing useful signal simultaneously, the top of circuit board 2 is provided with one deck radome 11, as shown in Figure 6, radome 11 and the opposite face of circuit board 2 are provided with deep mixed sunk structure 12, and the shape of radome 11 and size are decided by the circuit arrangement on concrete circuit board 2.Feed 3 also adopts disposable casting to form, and feed 3 is bolted on feed Connection Block 5 by the adpting flange 9 of front end, and adpting flange 9 is identical with the cavity mouth-shaped at probe cavity volume 6 place, preferably adopts rectangular through hole.
In the course of work, as shown in Figure 7, the microwave signal that feed receives directly sends into low noise amplifier circuit, as shown in Figure 8, in order to meet the requirement of system to noise factor, low noise amplifier circuit circuit selects the FET pipe with pole low-noise factor as active device, the requirement of low noise amplifier circuit to noise figure and gain is met by optimum noise figure matched design and maximum available gain matched design, mixting circuit is sent into through amplifying signal, as shown in Figure 9, in order to meet the demand of system gain and low local oscillation power, the active mixing structure of preferred employing FET pipe, as shown in Figure 10 and Figure 11, based on actual signal behavior, local-oscillator circuit preferably adopts DRO (dielectric oscillator) to export as local oscillation circuit, and adopt second amplifying circuit to carry out after amplification to local oscillation signal and feed signal carries out mixing, amplify in the signal feeding intermediate frequency amplifier circuit of mixing, as shown in figure 12, intermediate frequency amplifier circuit also adopts secondary to amplify, directly receiving equipment is sent into by signal output part after amplifying, in order to suppress image frequency and intermediate frequency interference, image frequency can be suppressed by adding bandpass filter with image suppression between low noise amplifier circuit and mixting circuit, in intermediate frequency amplifier circuit, add low pass filter disturb to suppress intermediate frequency.
