ABSTRACT
This article discusses the importance of the AD8368. This analog-control variable gain amplifier has the capability of prolonging high linearity at the highest intermediate frequencies. With the use of a 3-dB bandwidth of 800 MHz that is independent of gain setting, single-ended input and output drive and exceptional linearity, this mechanism could be ideally used in GSM, CDMA 2000, and TD-SCDMA cellular base stations and is developed to preserve the dynamic range of radio transceivers.
