摘要：
The features of Othello-G radio developed by Ananog Devices are discussed. It is compatible with GPRS Class 12 packet operation, featuring a duty cycle up to 50%. The radio's complete direct-conversion design integrates four fully gain-programmable low-noise amplifiers with a 77-dB gain control range. Three on-chip low-dropout regulators save space and let the device operate directly from a battery in the 2.9 to 5.5-V range. The device reduces component count in cell-phone designs by 75%.
