Embodiment Construction

[0026] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the spectrum inversion conversion system includes: a transmitting channel 1, a receiving channel 2, an antenna 3 and a duplexer 4. The transmission signal is transmitted to the antenna 3 after passing through the transmission channel 1, and the antenna 3 sends out the transmission signal; the antenna 3 outputs the received signal through the receiving channel 2.

[0028] In this embodiment, the transmission channel includes a signal source 101, a first mixer 102, a first filter 103, a first intermediate frequency amplifier 104, a third mixer 105, and a power amplifier 106 that are electrically connected in sequence, and the power amplifier 106 The output is connected to duplexer 4. The mixer 102 is also connected with a first frequency source 107 , the first frequency source 107 is connected with a single-chip microc...

Abstract

The invention discloses a frequency-spectrum inversion transformation system, comprising a first mixer connected in a transmission channel, a first frequency source connected with the first mixer, a second mixer connected with a receiving channel, a second frequency source connected with the second mixer, and a single chip microcomputer respectively connected with the first frequency source and the second frequency source, wherein the single chip microcomputer respectively controls signals emitted by the first frequency source and the second frequency source. According to the frequency-spectrum inversion transformation system disclosed by the invention, the signals input to the mixers from the frequency sources are adjusted by the single chip microcomputer, and the signals are mixed with transmission signals so as to obtain signals with the same phase or the reverse phase with the transmission signals, or the signals are mixed with receiving signals so as to obtain signals with the same phase or the reverse phase with the receiving signals. Furthermore, the frequency of the signals which are input to the mixers from the frequency sources is adjusted by the signal chip microcomputer, so that the obtained signals have the same frequency with the transmission signals or the receiving signals.

Description

technical field [0001] The present invention relates to a communication transmission system, in particular to a spectrum inversion transformation system. Background technique [0002] At present, each communication operator has different requirements for the spectrum phase in the communication link. As a result, it is necessary to use its dedicated communication equipment according to the difference of the communication equipment manufacturer when the communication network is set up to ensure the signal spectrum in the communication link. consistency. Once the equipment provided by other communication equipment manufacturers is used, there is no guarantee that the equipment can provide the same frequency spectrum as the original equipment in the communication link, because it cannot meet the requirements of the communication operators for the spectrum phase. In this case, only because of the difference in spectrum phase, the diversified selection of communication equipment ...
