这份报纸学习信号和二搬运人的 CW 在理论和模拟两个都表明的一个单个搬运人的连续波浪(CW ) 驾驶的力量放大器(PA ) 的行为,并且当一个二搬运人的 CW 信号被用于时,解释传统的双乐队的 PA 为什么没能执行令人满意的结果,并发地打电话。除那以外,并发的双乐队的 PA 的一个评估标准被介绍珍视它的表演。解决方案与一个同时发生的事件的设计和制造被给 1.85 GHz/2.65 GHz 类 F PA ,采用 10W 从克里族轧了 HEMT 设备, CGH40010 ,其大小显示出浸透的输出力量,分别地在 1.85 GHz 和 2.65 GHz 与77.4%和75.3%的排水管效率( DE )是 40.6 dBm 和 40.8dBm 。在另一方面,我们看到山峰 DE 在并发的模式与 39.9 dBm 的产量力量完成 59.7% ,它与标准列在后面在上面。
This paper studies the behaviors of power amplifier(PA) driven by a single-carrier continuous wave(CW) signal and a two-carrier CW signal both in theory and simulation, and explains why the traditional dual-band PA failed to perform satisfactory results when a two-carrier CW signal is applied to, called concurrently. Besides that, an evaluation standard of concurrent dual-band PA was presented to value its performance. Solution was given with design and fabrication of a concurrent 1.85 GHz/2.65 GHz class F PA, employing a 10 W GaN HEMT device from Cree, CGH40010, whose measurement shows the saturated output power is 40.6 d Bm and 40.8dB m with drain efficiencies(DE) of 77.4% and 75.3% at 1.85 GHz and 2.65 GHz, respectively. On the other hand, we see that the peak DE achieves 59.7% with an output power of 39.9 dB m in concurrent mode, which follows up with the standard.
