Abstract
The invention discloses a radio frequency head, comprising a radio frequency head part (3) and a wave guide cylinder (4) connected with the radio frequency head part (3), wherein the wave guide cylinder (4) is connected with a wave collector (6), the inner chamber wall of the wave guide wall (4) is provided with four planes (5) in parallel to the central axis of the wave guide cylinder (4), and the adjacent planes in the four planes (4) are vertical to each other. The invention has the advantage of rapid transmission speed without attenuation of linearly polarized wave in the transmission process.
Description
Technical field
The present invention relates to a kind of decoding and high-frequency signal amplifier that receives satellite TV signal, specifically relate to a kind of tuner.
Background technology
At present, Chang Gui tuner all will comprise tuner head and the guided wave tube of being located at lower head usually; Described guided wave tube below is connected with tubaeform interface (being commonly called as wave collecting device) usually again.Adopt the tuner of said structure in actual application, to have a weak point: because the inner chamber of above-mentioned guided wave tube is a cylindrical structural, and the line polarization wave of the waveform that tuner receives after generally all to be polarizer conversion after being installed in the reception antenna feed come, the round of line polarization wave in cylindrical guided wave tube can only be spiral, this mode transmission speed of line polarization wave that not only slowed down greatly by spiral routes line of propagation polarized wave, and make line polarization wave in transmission course because of the long strength retrogression's of generation of propagation time phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of not only transmission speed fast, and can not cause line polarization wave strength retrogression's tuner in transmission course.
In order to solve the problems of the technologies described above, the invention provides a kind of tuner with following structure: it comprises tuner head and the guided wave tube that is connected with the tuner head; Described guided wave tube is connected with wave collecting device; The internal chamber wall of described guided wave tube be provided with four with the parallel plane of guided wave tube central axis; Adjacent plane in described four planes is perpendicular.
After adopting above structure, the present invention has the following advantages: adopt cylindrical structural different with the inner chamber of guided wave tube in the prior art since the present invention on the internal chamber wall of waveguide pipe, be provided with four with the parallel plane of guided wave tube central axis; Adjacent plane in described four planes is perpendicular; Thereby make the rectangular structure of internal chamber wall of waveguide pipe of the present invention, therefore, the present invention can rely on the rectangular configuration of guided wave tube inner chamber the spiral circulation way of line polarization wave to be changed into the diagonal circulation way of line polarization wave, thereby not only improve the transmission speed of line polarization wave greatly, and avoided line polarization wave because of the shortening of propagation distance and time strength retrogression's phenomenon takes place in communication process.
