Problems solved by technology

Since the amplifier with this structure must be fixed on a fixed object, it has high requirements for circuit layout, and it is also inconvenient to construct.
Moreover, in many cases, it is necessary to run wires in the pipeline, and traditional amplifiers cannot enter the thinner pipelines, and at the same time, the larger amplifiers connected to the lines will also hinder the construction

Abstract

The invention discloses a coaxial integrated GPS line amplifier, comprising a housing and an amplifier body installed in the housing, wherein the input end and the output end of the amplifier body are respectively and electrically connected with a connector used for connecting cables, the housing is a tubular pipe sleeve, and the connector is fixed on two ends of the tubular pipe sleeve. By designing the housing into the tubular pipe sleeve and coaxially arranging with the cables, the amplifier can be directly arranged in a circuit and does not need to be fixed on a fixture, and meanwhile, wiring in a pipeline can be conveniently carried out.

Description

Technical field [0001] The invention relates to a line amplifier in the process of GPS signal transmission; it is suitable for use when the distance between a GPS base station antenna and a GPS receiver is greater than 100 meters, and particularly relates to a GPS line amplifier with a coaxial integrated design. Background technique [0002] The GPS signal transmitted from the GPS satellite is very weak, so the GPS receiver can track the satellite signal well and work stably. The GPS signal received is required to be very clean. Usually too long antenna RF cable and external electromagnetic interference will deteriorate the satellite signal received by GPS before entering the GPS receiver. The degree of deterioration depends on the type and length of the RF cable. Therefore, it is necessary to amplify the signal to be strong enough with high fidelity during the GPS signal transmission process, and then carry out long-distance transmission. Generally, an amplifier is added to the...
