摘要
基于AWSC 2μm的HBT工艺,设计了一种用于5G通信N77频段(3.3~4.2 GHz)的功率放大器。采用变压器匹配的方式,显著提高了功率放大器的增益、输出功率和功率附加效率,解决了放大电路级间匹配较难的问题。仿真和测试结果表明,在N77工作频段内,该功率放大器的增益为36~38 dBm,输出功率1 dB压缩点为37 dBm,输出功率1 dB压缩点处的功率附加效率为49.3%,输出功率28.5 dBm处的功率附加效率为16.5%、相邻频道泄漏比为-38.2 dBc。
Based on AWSC 2μm HBT process,a power amplifier applied in 5 G N77 frequency band(3.3~4.2 GHz)was designed.The gain,output power and power added efficiency of the power amplifier were significantly improved by using transformer matching.The problem of difficulty for matching the inter-stage of amplification circuits was solved.Simulation and test results showed that in the N77 operating band,the power amplifier had a gain of 36~38 dBm,an output power 1 dB compression point of 37 dBm,a power addition efficiency of 49.3%at 1 dB compression point output power,a power addition efficiency of 16.5%at 28.5 dBm output power,and an adjacent channel leakage ratio of-38.2 dBc.
