Title:
SIGNAL TRANSMITTER
Document Type and Number:
WIPO Patent Application WO/2021/115327
Kind Code:
A1
Abstract:
The present application provides a signal transmitter, which is able to improve the flexibility of signal decomposition of a transmitter and improve the system performance of the signal transmitter. The signal transmitter comprises: a signal decomposition module comprising M output interfaces, wherein the signal decomposition module is used to decompose a signal into N sub-signals, and output the N sub-signals by means of N output interfaces among the M output interfaces, M and N being integers, M≥2, N≥1 and M≥N; an integrated array travelling wave tube amplifier, comprising M radio frequency channels, wherein the M channels correspond to the M output interfaces on a one-to-one basis, each channel is used to perform power amplification on a sub-signal outputted from a corresponding output interface, and each channel is openable and closable; a power supply module, used to supply power to the integrated array travelling wave tube amplifier; and at least one transmitting antenna, used to send the signal on which power amplification has been performed.
