Description of the Invention: [Technical Field] The present invention relates to an adjustable satellite frequency conversion host, and more particularly to transducing the frequency of a received intermediate frequency signal into a fixed bandwidth in units of a frequency converter. The designated frequency band' is used to add more adjustable satellite transponders to the fixed bandwidth. [Prior Art] With the help of technology, people can get rich information from various media, such as the Internet, satellite TV, etc., because advanced countries have launched artificial satellites for military and commercial purposes, and satellite radio and television. It is the main commercial use - because of the use of satellites for broadcasting, in the knowledge that satellite signals can be covered, people can 'read'; two σ 礼 ® 1 们 q 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星 卫星Satellite TV shows. Because of the installation of satellite antennas, commonly known as small ears and large ears, they have been popular. In order to meet the demand for viewing satellite programs, many buildings have satellite broadband common antenna systems (950~2200MHz) for residents to watch TV programs. According to ___ viewing habits, the Japanese HCTEBS satellite channel is the basic and main receiving satellite 'others such as 115.K towel country satellite 6B because they can watch the channels of mainland TV stations and CCTV, so it is also the main receiving Weifu' other Such as 槪.5. £Asian Satellite 3 is a favorite satellite channel, and it is said that 'each satellite usually has multiple transponders to provide multiple channels. 'Some of these channels are paid viewers, and some are free viewers. For the viewers, whether or not the payment is usually one of the main reasons for determining whether or not to view it, in addition, the same channel of the same satellite does not necessarily have 3 200939765 is in line with the preferences of the viewers themselves, therefore, for the viewers Of course, I hope that the more free channels that I can watch, the better, and it is difficult to meet the expectations of the aforementioned viewers with the current satellite receiving technology. Take the satellites that the Chinese people like to watch, for example. The IF of the frequency converter usually falls between the first half of the broadband system and 45 〇MHz. 'If the broadband system first sets the BS satellite , the bandwidth is 1049M~1318MHz is occupied (please refer to the third figure). If you want to join the Asian satellite 3, there will be overlapping of the frequency bands. After receiving the signals from each of the Asian Satellites 3 transponders, they will be frequency-shifted. After the frequency-shifting, Asia Satellite 3 will use the bandwidth from 1350 MHz to 2200 MHz, but with this full-stage frequency-shifting method, The broadband system (95〇M~22〇〇MHz) can only accommodate 2 satellites at best, that is, if the viewers only use the free channel, that is, there are only 2 free channels in the satellite, but these free channels are available. The content of the program may not be able to meet the preferences of the viewers. Therefore, it is difficult to meet the requirements of the viewers by adopting the whole frequency of satellites. SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an adjustable satellite transponder capable of translating the frequency of the transponder to a fixed frequency in units of satellite transponders. The frequency band, by which more channels that meet the needs of the viewer can be accommodated in the existing broadband system.
