Problems solved by technology

[0007] Techniques for reducing such errors have been able to adjust signal levels based solely on direct current (DC) through structures such as mirror circuits, but have limited application in adjusting suddenly changing signal levels
Especially in the case of systems using high frequency bands (e.g. 5G), signal processing and communication results can present serious problems

Abstract

A method and apparatus capable of adjusting a signal level in a wireless communication system are provided. An electronic device includes an oscillator configured to output a local oscillator (LO) signal, a mixer configured to convert a frequency band of a first signal based on the LO signal and output a third signal, and a feedback circuit configured to output a feedback signal for adjusting a magnitude of the LO signal, wherein the mixer is further configured to adjust a magnitude of LO signal based on the feedback signal.

Description

technical field [0001] The present disclosure relates to apparatus and methods for sensing and adjusting for changes in signal levels. Background technique [0002] In order to meet the increased demand for wireless data services after the commercialization of the fourth generation (4G) communication system, efforts to develop an improved fifth generation (5G) communication system or pre-5G communication system have been made. Therefore, the 5G communication system or pre-5G communication system is called a super 4G network communication system or a post-Long Term Evolution (LTE) system. In order to achieve a high data transmission rate, implementation of a 5G communication system in the mmWave frequency band (eg, 60GHz frequency band) is being considered. In 5G communication systems, technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-scale MIMO (FD-MIMO), array antennas, analog beamforming, and large antennas are being discussed as mitiga...
