摘　　要：传输带宽和效率一直是短距离通信传输的两项重要技术指标。如何使功放工作在宽频带的同时兼具高效率是业内的研究难点与热点。通过对F/F-1类功放的研究,在漏极电压中引入修正因子扩大阻抗匹配空间。将传统的F/F-1类功放拓展至连续F/F-1类功放。推广的连续型F类功放有效地提高了工作带宽。通过测试,该款功放工作在1~3 GHz内,功放的增益大于11 dB,饱和输出功率大于41 dBm,功率附加效率为57%~73%。将该款功放与近几年的超宽带功放性能进行比较,很明显在保证了高倍频程的前提下具有更高的效率和更紧凑的结构。说明实验设计是可行的,能够很好地适应5G的短距离通信传输。Transmission bandwidth and efficiency are two important technical indicators in short-distance communication.It is a research difficulty and hot spot in industry to understand how to make broadband power amplifier with high efficiency.Here by studying class F/F-1 power amplifier,a correction factor was introduced into drain voltage to improve impedance matching.The traditional class F/F-1 power amplifier was extended to a continuous class F/F-1 power amplifier,which effectively improves the working bandwidth.Test results show that the power amplifier can work from 1 to 3 GHz with gain of greater than 11 dB,saturated output power of greater than 41 dBm,and power additional efficiency of 57%-73%.Comparing with other ultrawideband power amplifiers in recent years,it has higher efficiency and more compact structure under the premise of ensuring high octave.It shows that the design is feasible and can be well adapted to short-distance 5G communication.
