Title:
SILICON-BASED TIME MODULATION PHASED ARRAY FEED NETWORK UNIT AND TIME MODULATION PHASED ARRAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/130765
Kind Code:
A1
Abstract:
Disclosed is a silicon-based time modulation phased array feed network unit, characterized in comprising a power division module, a time modulation module, an orthogonal synthesis module, and an amplifier module. In a signal transmission process, a transmitted signal enters the time modulation module by means of the power division module, or directly enters the time modulation module. After signal phase shifting is completed in the time modulation module, in-phase/orthogonal transformation and power synthesis are carried out on the phase-shifted signal by the orthogonal synthesis module, and the signal is then amplified by the amplifier module and outputted. In a signal reception process, after a radio-frequency signal has been amplified by the amplifier module, the radio-frequency signal is subjected to power division and in-phase/orthogonal transformation by the orthogonal synthesis module, and then enters the time modulation module to carry out signal phase shifting, and the phase-shifted signal is synthesized and outputted by the power division module or is directly outputted. The present invention is simple in structure, improves the phase shift precision of the system, and reduces the loss of the system.
