Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] see Figure 1 to Figure 3 , the software-controlled adjustable phase shifter provided by the present invention includes a housing, a data interface is provided on one side of the housing, and a driving mechanism, a sliding mechanism, a control system, a connecting line 22, an internal and external Conductor set 23 , outer conductor set 24 , inner conductor set 26 and joint 27 .

[0022] The connection line 22, the inner and outer conductor groups 23, the outer conductor group 24, the inner conductor group 26 and the joint 27 are sequentially connected coaxially and horizontally in the casing, thereby forming a coaxial transmission system, so that external control commands can be transmitted to the Control system, the control system contr...

Abstract

The invention discloses an adjustable phase shifter being controllable by software. The adjustable phase shifter comprises a housing; and a data interface is arranged at one side of the housing. A driving mechanism, a sliding mechanism, a control system, a connection line, an inner-outer conductor group, an outer conductor group, an inner conductor group and a joint are arranged inside the housing. The data interface is connected with an external data input terminal cooperatively. The control system is respectively connected with the data interface and the driving mechanism; and the driving mechanism is connected with the sliding mechanism. The connection line, the inner-outer conductor group, the outer conductor group, the inner conductor group and the joint are connected successively, coaxially, and horizontally; and the inner-outer conductor group and the sliding mechanism are in cooperative connection. Therefore, under the circumstance that the circuit of the radio frequency transmission system is not interrupted, delay of a signal is changed continuously; the phase of the measurement system is adjusted in an online manner by software control; the automatic test need of the modern communication system is met; the manpower and material resources are saved substantially; and the efficiency is improved.

Description

technical field [0001] The invention relates to an adjustable phase shifter, in particular to an adjustable phase shifter which can be controlled by software. Background technique [0002] Phase shifters are required in phased array radar, microwave communications, missile attitude control, accelerators, satellite technology, instrumentation, etc. [0003] In the past, the phase adjustment of communication base stations and repeaters used a manual phase shifter, but it has the following disadvantages in actual commissioning: [0004] The manual phase shifter uses manual adjustment to change the phase. The adjustment speed of the manual phase shifter is slow and the adjustment consistency is poor. It cannot meet the test requirements of automatic programmed remote control of modern communication systems. [0005] Therefore, aiming at the defects of the prior art structure, an adjustable phase shifter that can be controlled by software is needed to solve the deficiencies of t...
