Description

Technical Field

[0001] This invention relates to the field of private network communication technology, and in particular to a circuit control system for an electronically controlled combiner. Background Technology

[0002] With the rapid development of communication networks and the gradual increase in the number of mobile phone users, base stations need to have more and more carrier frequencies to meet the requirements of high traffic capacity. However, traditional multi-carrier combiners are divided into two types: one is a broadband combiner implemented by a 3dB bridge, which can be used in a certain frequency band and does not require tuning; the other is a multi-carrier base station private network frequency combining system formed by combining multiple single-cavity series isolators.

[0003] Traditional multi-carrier combiners have low isolation between channels and high channel loss. During site construction, the frequency points need to be manually tuned or customized according to the planned frequency points. They cannot automatically adjust the combiner channel frequency points, so they cannot be stocked and produced in bulk in advance, and lack flexibility. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low isolation between channels, high channel loss, the need for manual frequency tuning during site construction, or customization based on planned frequencies, the inability to automatically adjust the combiner channel frequencies, and the lack of flexibility in advance batch preparation and production. Therefore, this invention proposes a circuit control system for an electrically adjustable combiner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit control system for an electrically tunable combiner includes a mounting plate. An L-shaped fixing member is provided on one side of the mounting plate, and a housing is provided on one side of the L-shaped fixing member. The housing is fixed to the mounting plate via the L-shaped fixing member. A dual-directional coupling connector is fixedly installed at the center of the upper end of the housing. Single-cavity filters are symmetrically installed at both ends of the dual-directional coupling connector. Isolators are installed on both sides of the single-cavity filters. A motor base is fixedly installed on the upper end of the housing near the single-cavity filters. A motor is fixedly installed on the upper end of the motor base, and the motor is fixed to the cavity of the single-cavity filter via the motor base. A resonant cavity housing is provided inside the housing. A resonant rod is provided inside the resonant cavity housing. The resonant rod is located on one side of the upper end of the resonant cavity housing and directly below the motor base. A tuning rod is sleeved on the lower end of the resonant rod, and the tuning rod is movably connected to the resonant rod.

[0007] Preferably, the lower end of the motor is provided with a connecting rod, which passes through the resonant rod, the tuning rod and the top of the housing to reach the outside of the housing and is connected to the central rotating shaft of the motor.

[0008] Preferably, the housing is provided with various ports, which are connected to the motor and the dual-directional coupling connector via coaxial cables.

[0009] Preferably, the central shaft of the motor is concentrically connected to the tuning rod.

[0010] Preferably, the isolator is connected in series with the single-cavity filter.

[0011] Preferably, the outer surface of the mounting plate is provided with mounting holes, and the mounting plate is fixed to the cavity of the single-cavity filter by screws and mounting holes.

[0012] Preferably, the dual directional coupling connector is connected to the single-cavity filter via a coaxial cable.

[0013] Compared with the prior art, the present invention provides a circuit control system for an electrically regulated combiner, which has the following beneficial effects:

[0014] 1. The circuit control system of this electrically tunable combiner is a unit for each channel. Each unit consists of a single-cavity filter, an isolator, a motor, and a dual-directional coupling connector. It can flexibly perform multi-carrier combining. The motor is fixed to the cavity of the single-cavity filter through the motor base. The central shaft of the motor is concentrically connected to the tuning rod. By rotating the motor, the length of the tuning rod is changed, thereby changing the product frequency. Within a certain frequency range, the frequency of the combiner channel can be automatically adjusted. It is simple to operate, highly applicable, greatly increases the flexibility of site construction, and can be pre-processed and produced according to the frequency band.

[0015] 2. The circuit control system of this electrically tunable combiner connects an isolator in series with the single-cavity filter of each channel, thereby greatly improving the isolation between channels, making the isolation between channels as high as 70dB, and reducing channel losses.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description
