If the user wants also to receive the low frequency broadcast television signal receiving on the basis of satellite TV signal, installation room outside antenna in addition, and this exterior aerial is inserted indoor, very bother.
The utility model content
Technical problem of the present utility model is how to overcome existing tuner can not receive low frequency broadcast television signal defective, provides a kind of multi-functional KU frequency range satellite to receive tuner and corresponding receiving system, and the outer inhibition of band reaches or greater than 30dB, two kinds of signals do not disturb mutually.
For solving the problems of the technologies described above, this multi-functional KU frequency range satellite receives tuner, comprise feed, the high frequency tuner circuit assembly, wherein the high frequency tuner circuit assembly comprises low-noise wide-band amplifier, power divider, mirror image inhibition zone bandpass filter, two local oscillator oscillators, balanced mixer, intermediate frequency amplifier and control circuit, it is characterized in that: it also comprises outside broadcast television antenna signal input part, be provided with the high pass filter of 950-2150MHz between intermediate frequency amplifier and the tuner output, outside broadcast television antenna signal input part joins by low pass filter and the tuner output of 47-862MHz.
During use, from the radiofrequency signal of satellite repeater after the tuner frequency reducing, amplifying, through the 950-2150MHz high pass filter filters, obtain pure high frequency satellite TV signal, after radiated television signal that exterior aerial receives and the stack of high frequency satellite TV signal, together import into indoor, last, by channel-splitting filter with two kinds of Signal Separation after, supply with television set.(the outer inhibition of the band of 47-862MHz low pass filter and 950-2150MHz high pass filter all reaches or greater than 30dB, so basic between them do not have to disturb, can transmit on same holding wire)
So design, the user only just can with satellite TV signal and the access of radiated television signal be indoor, simple in structure, easy to connect, cost is low with a signal line.
As optimization, output has two or more.So design can provide signal for two or two above television sets.
The utility model also relate to a kind of can compatible radiated television signal and the receiving system of KU frequency range satellite TV signal, comprise tuner, it is characterized in that: described tuner is that aforementioned multi-functional KU frequency range satellite-signal receives tuner, be provided with channel-splitting filter between this tuner and the television set, the input of this channel-splitting filter and the output of tuner join, its output has two, exports the low frequency radiated television signal of 47-862MHz and the high frequency satellite TV signal of 950-2150MHz respectively.47-862MHz low frequency radiated television signal can directly be imported television set, and the high frequency satellite-signal of 950-2150MHz needs to import television set again after satellite receiver is handled.
The Ku frequency range tuner that the utility model provides is a kind of bipolarity, two local oscillator (9.75GHZ and 10.6GHZ), the frequency demultiplier of dual output, it and parabolic antenna and satellite television receiver are combined, constitute the satellite television earth receiving station, can directly receive the analog or digital TV signal that geostationary satellite Ku band transponder is sent, if the supply broadcast television signal can also be used to watching common cable television program.
