Problems solved by technology

[0010] However, in the case of a wireless communication device equipped with an RF module configured such that RFA and RFB are connected using a single cable, it is difficult to implement a loopback path for phase calibration
For example, almost all wireless communication devices supporting mmWave frequency bands employ a time division multiple access (TDMA) scheme, so transmission (TX) and reception (RX) cannot be performed simultaneously
As a result, the wireless communication device cannot simultaneously perform transmission and reception of test signals for calibration, so that it is not easy to measure the performance of the RF module and calibrate the phase based thereon

Abstract

An apparatus and method for phase calibration in a radio frequency (RF) module constituting a wireless communication device are provided. The apparatus and method include: transmitting a test signal by a forward transmit antenna array of a first antenna array; and receiving, by a forward receive antenna array of a second antenna array The transmitted test signal. Based on the received test signal, a phase value associated with each of the chain combinations formed by the first antenna array and the second antenna array is calibrated. The forward chain combination constituting the chain combination may be determined by a combination of: a forward transmit chain corresponding to each of the transmit antennas constituting the forward transmit antenna array; and a forward receive chain composing the forward receive The respective receiving antennas of the antenna array correspond to each other.

Description

technical field [0001] The present disclosure relates to an apparatus and method for phase calibration in a radio frequency (RF) module constituting a wireless communication device. Background technique [0002] Efforts have been made to develop improved fifth-generation (5G) communication systems or quasi-5G communication systems to meet the growing demand for wireless data services since the commercialization of fourth-generation (4G) communication systems. For this reason, a 5G communication system or a quasi-5G communication system is called a beyond 4G network communication system or a post-Long Term Evolution (LTE) system. [0003] In order to realize a high data transmission rate, realization of a 5G communication system in a millimeter wave frequency band (for example, a 60 GHz frequency band) is being considered. In order to reduce the path loss of radio waves and increase the propagation distance of radio waves in millimeter waves related to 5G communication syste...
