摘要
本文总结了极性调制放大器线性化的优点，说明了极性发射机中高性能电源调制器的必要性。介绍了两种可能的调制器方案;两者都在4 MHz和20 MHz之间占用RF带宽和超过65 dB SFDR。这些调制器处理包络信息1625 kb/s 8PSK和CDMA IS95应用在极性PA架构。所提出的电路和信号处理技术可以推广到未来的调制器设计中。
This paper summarizes the advantages of PA linearization via polar modulation and illustrates the necessity for high-performance supply modulators in polar transmitters. Two potential modulator solutions are introduced; both having between 4 MHz and 20 MHz occupied RF bandwidth and more than 65 dB SFDR. These modulators process envelope information for 1625 kb/s 8PSK and CDMA IS95 applications in polar PA architectures. The presented circuits and signal processing techniques can be generalized for future modulator designs.
