US 2019/0379385 A1 · ELECTRONIC DEVICE INCLUDING PLURALITY OF PHASED LOCKED LOOP CIRCUITS

Abstract

A communication technique for converging internet of everything (IoT) technology with a 5th generation (5G) communication system for supporting a higher data transfer rate beyond a 4G system is provided. The communication technique can be applied to intelligent services, based on 5G communication technology and IoT-related technology. In an embodiment, an electronic device includes a first processor configured to output a first signal for generating a first frequency signal, a second processor configured to output a second signal for generating a second frequency signal, a first radio frequency (RF) chip configured to output the first frequency signal, based on the first signal received from the first processor and a baseband signal, and a second RF chip configured to output the second frequency signal, based on the second signal received from the second processor and the first frequency signal outputted from the first RF chip.
