1现有功率放大器特征化技术的挑战1.1面临的挑战在不牺牲测量精度或提高设备成本的情况下,缩短对日益复杂的无线功率放大器(PA)的特征化时间。尽管无线射频功率放大器主要设计是在单频带单模式下工作,但是现代功率放大器要满足更为多样化的需求。实际上,现代功率放大器的设计可以工作在8个或更多频带下,并且能够用于包括GSM、EDGE、WCDMA、HSPA+、LTE等多种调制类型。使用NI PXI,能够将新组件的特征化时间从两 1 Existing Power Amplifier Characterization Challenges 1.1 Challenges Reduce the characterization time of an increasingly complex Wireless Power Amplifier (PA) without sacrificing measurement accuracy or increasing equipment costs. Although the main design of RF power amplifiers is to operate in single-band single mode, modern power amplifiers have to meet more diverse needs. In fact, modern power amplifiers are designed to operate in eight or more frequency bands and can be used in a variety of modulation types including GSM, EDGE, WCDMA, HSPA +, LTE, and the like. With NI PXI, you can characterize new components from two
