And embodiment, to specific embodiment of the present utility model, structure feature and its effect, detailed description are as follows.
Embodiment 1:
It uses multiple feeder equipments for relevant device feed to solve existing satellite communication portable formula antenna, causes to present
Electric at high cost, high failure rate, and inconvenient problem is repaired, the present embodiment provides a kind of satellite communication portables as shown in Figure 1
The feeder equipment of formula antenna, including for converting voltage source adapter 1, power divider A2 and power divider B3, wherein
The output end of power supply adaptor 1 is connect with the non-of power divider A2 every value end 22, the end IN 23 of power divider A2 and high frequency
First 5 connection, the DC voltage that power supply adaptor 1 exports are exported from the end IN 23 of power divider A2 to tuner 5, logical to realize
The end IN 23 of overpower distributor A2 is the feed of tuner 5；The output end of power supply adaptor 1 is non-every value with power divider B3's
32 connection of end, the end IN 33 of power divider B3 connect with power amplifier 4, and the DC voltage of the output of power supply adaptor 1 is from function
The output of the end IN 33 of rate distributor B3 is to power amplifier 4, to realize that by the end IN 33 of power divider B3 be power amplification
Device 4 is fed.
It should be pointed out that it is above-mentioned it is non-refer to every value end can be by direct current signal, and AC signal cannot pass through；
It is then isolated DC signal every value end, only AC signal can pass through.In conjunction with power divider every value port and it is non-every
The isolation being worth between port, so that, when power supply adaptor 1 exports the DC voltage of DC18V ~ 24V from power divider A2's
Non- the voltage is only exported from the end IN 23 of power divider A2 after being worth 22 ingoing power distributor A2 of end, without from power
Distributor A2's exports every value end 21, since the end IN 23 of power divider A2 is connect with tuner 5, from power distribution
The DC voltage that the end IN 23 of device A2 exports can be fed to tuner 5；Similarly, when power supply adaptor 1 exports the straight of DC18V ~ 24V
Galvanic electricity pressure is from the non-after being worth 32 ingoing power distributor B3 of end of power divider B3, and the DC voltage is only from power divider B3
The end IN 33 export, since the end IN 33 of power divider B3 is connect with power amplifier 4, from power divider B3's
The DC voltage that the end IN 33 exports can be fed to power amplifier 4.
The power divider of the present embodiment is one-to-two power divider, can also be called dual-frequency channel merger.Above by
Two power dividers give power amplifier and tuner to feed respectively, are the combiner principles that power divider is utilized, only
It is the synthesis channel all the way for having used each power divider respectively, another channel Zhi Hecheng is vacant.
The feeder equipment of the satellite communication portable formula antenna of the present embodiment can be realized only by 2 power dividers with one
A feeder equipment is multiple relevant device tuners 5, the feed of power amplifier 4 simultaneously, so that the structure of feeder equipment is simple, connects

Reception.
In addition, the power divider B3's of the present embodiment connect every value end 31 with the signal output end of terminal device, at this time
Terminal device, power divider B3, power amplifier 4 and antenna surface constitute the transmitting road of transmitting signal；Specifically, terminal is set
Preparation go out transmitting signal entering in power divider B3 every value end 31 from power divider B3, then due to every be worth end and
The non-isolation every value end, the transmitting signal can only be exported from the end IN of power divider B3 to power amplifier 4, power amplification
4 pairs of transmitting signals of device pass to antenna surface after handling again, and by antenna surface, by treated, transmitting signal emits into space.
As shown in Figure 1, the output end of power supply adaptor 1 is non-every value end 22, power distribution with power divider A2 respectively
The non-of device B3 connects every value end 32；The signal output end of antenna surface is connect with the signal input part of tuner 5, the letter of tuner 5
Number output end is connect with the end IN 23 of power divider A2, and power divider A2's inputs every the signal of value end 21 and terminal device
End connection；In addition, the signal output end of terminal device and power divider B3's connect every value end 31, the IN of power divider B3
End is connect with the input terminal of power amplifier 4, and the signal output end of power amplifier 4 and the signal input part of antenna surface connect.
Power divider A2 had both passed through the non-every the combination of value end 22 power divider A2's of power divider A2 in this implementation
The end IN 23 is that tuner 5 provides operating voltage, at the same by the end IN 23 of power divider A2 combine power divider A2 every
It is worth end 21 for tuner 5 from the received satellite signal transit of antenna surface to terminal device.Similarly, in the present embodiment, power distribution
Device B3 both passed through its it is non-every value end 33 combine its end IN 33 to power amplifier 5 provide operating voltage, meanwhile, power divider B3
Complete in conjunction with the end IN 33 of power divider B 3 communication between terminal device and power amplifier every value end.
So set, 5 branch of tuner breaks down and will not influence the normal work of 4 branch of power amplifier, accordingly
4 branch of power amplifier breaks down and will not influence the normal work of 5 branch of tuner, therefore, convenient for the failure of antenna
Investigation, is also convenient for safeguarding, simplifies malfunction elimination program, saves maintenance time.
Further, power divider A2's is non-every value output of the end 22 by N-N power cables and power supply adaptor 1
End connection, the end IN 23 of power divider A2 is connect by F-F RF cables with tuner 5；Power divider B3 it is non-every
Value end 32 is connect by N-N power cables with the output end of power supply adaptor 1, and the end IN 33 of power divider B3 exports, and
