Abstract
A tower mounted amplifier is provided. The tower mounted amplifier includes: a first port, connected to an antenna of a base station; a first band-pass filter, where an input end of the first band-pass filter is connected to the first port; a first amplifier, where an input end of the first amplifier is connected to an output end of the first band-pass filter; a second band-pass filter, where an input end of the second band-pass filter is connected to an output end of the first amplifier, connected to an output end of the second band-pass filter and the base station.
Claims10
A tower mounted amplifier, comprising:
- a first port (201), connected to an antenna, and configured to perform signal interaction with the antenna;
- a first band-pass filter (202), wherein an input end of the first band-pass filter (202) is connected to the first port (201), and the first band-pass filter (202) is configured to obtain signals in at least two frequency bands through separation from uplink signals that are sent by the antenna and received by the first port (201);
- a first amplifier (203), wherein an input end of the first amplifier (203) is connected to an output end of the first band-pass filter (202), and the first amplifier (203) is configured to amplify the uplink signals that are in the at least two frequency bands and that are output by the first band-pass filter (202);
- a second band-pass filter (204), wherein an input end of the second band-pass filter (204) is connected to an output end of the first amplifier (203), and the second band-pass filter (204) is configured to receive the amplified uplink signals that are in the at least two frequency bands and that are output by the first amplifier (203);
- and
- a second port (205), connected to an output end of the second band-pass filter (204) and a base station, and configured to output, to the base station, the amplified uplink signals that are in the at least two frequency bands and that are output by the second band-pass filter (204).
The tower mounted amplifier according to claiml, wherein the tower mounted amplifier further comprises a sixth band-pass filter (501), an output end of the sixth band-pass filter (501) is connected to the first port (201), an input end of the sixth band-pass filter (501) is connected to the second port (205), and the sixth band-pass filter (501) is configured to:
- obtain a downlink signal in at least one frequency band through separation from the downlink signals that are sent by the base station and received by the second port (205), and output the downlink signal in the at least one frequency band to the antenna by using the first port (201).
