摘要

介绍了一种集成c类功率放大器(PA)的1.55GHz CMOS射频发射机。发射器使用笛卡尔反馈来满足EDGE线性度要求，并在0.18 μ m CMOS工艺中集成了直接转换调制器，PA, LO移相器，反馈混频器和基带环路滤波器。发射机产生18dBm EDGE调制输出，漏极效率为18%

A Cartesian-Feedback Linearized CMOS RF Transmitter for EDGE Modulation

A 1.55GHz CMOS RF transmitter with an integrated class-C power amplifier (PA) is described. The transmitter uses Cartesian feedback to meet EDGE linearity requirements and integrates a direct-conversion modulator, PA, LO phase shifter, feedback mixers and baseband loop filter in a 0.18mum CMOS process. The transmitter produces an 18dBm EDGE modulated output with 18% drain efficiency
