Title:

DOUBLE-FREQUENCY PHASED ARRAY

Document Type and Number:

WIPO Patent Application WO/2016/179799

Kind Code:

A1

Abstract:

Disclosed is a double-frequency phased array, used for solving the problem of independent occupation of resources by two frequency bands in a double-frequency phased array in the prior art, and saving system resources. The double-frequency phased array comprises: a frequency modulation module and a phase shift module connected to the frequency modulation module. The frequency modulation module is configured for frequency modulation between a baseband signal and an intermediate frequency signal. The phase shift module is configured for series-feed phase shift between the intermediate frequency signal and a series-feed phase shift signal. The phase shift module comprises a first coupler and a phase shifter. The first coupler is connected in series to the phase shifter. The first coupler is configured for directional coupling between the intermediate frequency signal and the series-feed phase shift signal. The phase shifter is configured for phase shift between the intermediate frequency signal and the series-feed phase shift signal.
