The invention relates to a feed amplifier. The amplifier comprises a power supply module, a power supply isolation module, a power supply feed-in module, a duplexer I, a duplexer II, a PA power amplifier and an LNA low-noise amplifier, the power supply isolation module is connected with the power supply module, wherein the power supply module is connected with the PA power amplifier, the LNA low-noise amplifier and the power supply feed-in module, the PA power amplifier and the LNA low-noise amplifier are connected in parallel and are both connected with the duplexer I and the duplexer II, theduplexer I is connected with the power supply isolation module, and the duplexer II is connected with the power supply feed-in module. The feed amplifier provided by the invention does not need to take power on site when a previous line supplies power, so that the stability of the system is improved; power can be supplied to an output line, so that the power supply problem of various devices fused with the line is effectively solved; due to line feeding of the output end, whether the working state of each equipment device is normal or not can be detected in time through the line power supplydetection system.
Description
technical field [0001] The invention relates to the field of amplifiers, in particular to a feed amplifier. Background technique [0002] At present, the amplifiers used in the wireless communication system and the next-level line equipment of the amplifier are powered on-site, and there are the following problems in the on-site power supply: the installation site needs to be equipped with a separate power supply device, and the system cost is high; In the same way as the UPS power supply in the computer room, there will be a local failure of no signal due to the interruption of the on-site power supply; the existing amplifiers do not have the function of supplying power to the output line, which greatly limits the structure of the line equipment and the Internet of Things equipment. fusion. Contents of the invention [0003] The purpose of the present invention is to provide a feed amplifier to solve the problems in the prior art that the amplifier and its next-level lin...
