Abstract
Description
technical field
[0001] The invention relates to a mobile phone communication electronic device, in particular to a mobile phone signal booster. Background technique
[0002] Mobile phone has become a kind of indispensable communication tool for people at present. When using a mobile phone, the signal is poor, and the problem of being unable to call or be called often occurs. These problems are mainly reflected in:
[0003] The outdoor street has a good signal, and the indoor signal is poor. This is the most common situation, mainly caused by the surrounding buildings blocking the signal of the base station.
[0004] There is a weak signal outdoors, but there is basically no signal indoors. The poor signal is due to the lack of dense base stations in rural and suburban areas, and some places are far away from the base stations, resulting in weak signals.
[0005] The outdoor street has a good signal, and there is basically no signal indoors. The poor signal is because t...
Examples
Embodiment Construction
[0019] see figure 1 , a mobile phone signal booster, comprising an outdoor antenna, a coaxial cable, a power divider, a coupler, an indoor antenna and a power supply, wherein the outdoor antenna is wired with the power divider through a coaxial cable, and the power divider, the coupler and the indoor The antennas are connected in sequence, and the power supplies are respectively connected to the power splitter and the coupler. The wire impedance of the outdoor antenna is 50 ohms. Coaxial cables are 50-7 or 50-12(1 / 2) or 50-22(3 / 4) wires. The power divider is a microstrip power divider wired in parallel. The couplers are wired in series; the N outdoor antennas need N-1 couplers.
[0020] The outdoor antenna connects the outdoor signal by cable, amplifies the downlink through the power divider and coupler, and then transfers it to the room to make up for the blind spot of the mobile phone base station; then passes the mobile phone signal through the uplink of the coupler and ...
