Abstract

Embodiments of methods and systems for attenuator phase compensation are described. In an embodiment, a method for attenuator phase compensation involves determining a phase compensation value for anattenuator based on an attenuation configuration of the attenuator and performing phase compensation according to the phase compensation value to maintain a constant phase response.

Description

Technical field [0001] The present invention relates to a method for phase compensation of an attenuator, and in particular to determining a phase compensation value of the attenuator based on the attenuation configuration of the attenuator, and performing phase compensation according to the phase compensation value to maintain a constant phase response. Background technique [0002] The attenuator can be used to reduce the amplitude of the electronic signal. For example, radio frequency (RF) attenuators are used to reduce the amplitude of RF signals. However, the setting of the attenuator may affect the phase response of the attenuator, which may adversely affect the performance of the corresponding communication device. For example, under certain attenuation settings, an automatic gain control (AGC)-based RF attenuator may exhibit a non-constant phase response. Summary of the invention [0003] An embodiment of a method and system for attenuator phase compensation is described...
