The utility model provides a tuner of big dipper satellite signal and DTMB signal simultaneous output, includes receiving antenna, frequency divider, tuner mainboard, blender, big dipper signal output part and DTMB signal output part, receiving antenna connects the frequency divider, the frequency divider is connected with blender and DTMB signal output part respectively, the blender with tuner mainboard 3 is connected to be connected with big dipper signal output part, realize big dipper signal output.
Preferably, the receiving frequency of the receiving antenna is 45MHZ-1650MHZ.
Preferably, the frequency divider is an RLC electronic frequency divider.
Preferably, a signal amplifier is arranged between the frequency divider and the mixer 4.
Has the advantages that: the utility model provides a tuner of big dipper satellite signal and DTMB signal simultaneous output can realize that big dipper satellite signal and DTMB signal adopt same tuner to receive and export.
Drawings
Figure 1 is a schematic diagram of the system of the present invention,
description of reference numerals:
reference numbers in the figures: a receiving antenna 1; a frequency divider 2; a tuner main board 3 and a mixer 4; a Beidou signal output end 5; a DTMB signal output terminal 6; a signal amplifier 7.
Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
Example 1:
as shown in fig. 1, a tuner of big dipper satellite signal and DTMB signal simultaneous output, including receiving antenna 1, frequency divider 2, tuner mainboard 3, blender 4, big dipper signal output part 5 and DTMB signal output part 6, receiving antenna 1 connects frequency divider 2, frequency divider 2 is connected with blender 4 and DTMB signal output part 6 respectively, blender 4 is connected with tuner mainboard 3, and be connected with big dipper signal output part 5, realize big dipper signal output, receiving antenna 1's receiving frequency is 45MHZ-1650MHZ, frequency divider 2 is RLC electron frequency divider.
Generally, the Beidou signal needs signal gain, a signal amplifier 7 is arranged between the frequency divider 2 and the mixer 4, and the signal amplifier 7 is a single-stage signal amplifier.
The working principle is as follows: receive signals through receiving antenna 1, distribute 49MHZ-900 MHZ's signal to DTMB signal output 6 through frequency divider 2 and export, distribute 1100MHZ-1650MHZ to blender 4, tuner mainboard 3 mixes the integration with big dipper signal at blender 4, finally exports through big dipper signal output 5.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
