Problems solved by technology

[0003] The current mobile communication base station antenna system transmits radio frequency signals through an independent feeder cable, and another cable transmits the control signal of the remote electric adjustable mobile antenna separately. In this way, the same electric adjustable antenna system needs to use two feeder cables and control cables during base station construction. Cables are used for signal control and radio frequency transmission of the antenna system, which increases the construction cost of the mobile communication system, increases the construction cost and maintenance difficulty, and has certain maintenance safety hazards

Abstract

The invention discloses a tunable antenna modulation-demodulation communication system which comprises a plurality of tunable antenna modulation-demodulation control devices. The tunable antenna modulation-demodulation control devices are connected through coaxial antenna feeder electric cables. Each tunable antenna modulation-demodulation control device comprises a composite signal control circuit and a coaxial signal transmission connecting cavity component which are connected to achieve data double-way transmission. The tunable antenna modulation-demodulation communication system can achieve effective composition of a direct current power supply signal, a tunable antenna control signal and a tunable antenna radio-frequency signal, radio-frequency spectral bandwidth is 645-2700MHz, current 2G and 3G mobile communication spectrum resources are compatible, cost of mobile communication base station building is really lowered, and reliability of mobile communication base station tunable antenna control is improved.

Description
