Embodiment Construction

[0029] The present invention overcomes the deficiencies of the prior art, and provides a broadband phase equalization method suitable for array transponders. Through the dispersion characteristics of the transmission line, the full bandwidth of the multi-channel system link of the array transponder or the multi-channel active stand-alone in the system is adjusted. The phase imbalance of the array transponder is equalized to achieve the control purpose of the phase consistency of the array transponder.

[0030] The specific idea of ​​the phase equalization method of the present invention: microwave channel phase with relatively long phase+correspondingly short transmission line phase=microwave channel phase with relatively short phase+correspondingly long transmission line phase, use the transmission line to realize the equalization of phase consistency within the microwave channel bandwidth , to realize the phase consistency of each microwave channel in the system;

Abstract

The invention discloses a bandwidth phase equalization method suitable for an array transponder. The phase unbalance in a full-bandwidth of a multi-channel active single-machine in a multi-channel system link or system of the array transponder is equalized through the dispersion characteristic of a transmission line, thereby achieving a control aim of phase consistency in the full-work bandwidth of the array transponder. The method disclosed by the invention is mainly used for effective load of a static orbit mobile communication satellite using the array transponder. Through the method provided by the invention, the requirement on phase consistency in the multi-channel full-work bandwidth by the array transponder can be realized, the power integration capacity, the beam forming precisionand like main performance indexes related to the phase consistency of the array transponder are improved, and the performance of the array transponder is promoted.

Description

technical field [0001] The invention relates to the payload technology of a geostationary orbit mobile communication satellite, in particular to a broadband phase equalization method suitable for an array transponder. Background technique [0002] The array transponder is the core technology of the geostationary orbit mobile communication satellite, and usually includes dozens or even hundreds of receiving and transmitting channels. In order to achieve dynamic power allocation in the transmission channel, the Butler matrix + fixed amplifier is generally used to form a dynamic power allocation. The amplitude and phase consistency of dozens of solid-state amplifiers will affect the output power and synthesis efficiency, thereby affecting the beamforming; the receiving channel usually uses dozens of channels Even hundreds of low-noise amplifiers receive user signals at the same time. The amplitude-phase consistency of the low-noise amplifier will affect the beam formation. Ther...
