摘　　要：该文设计了一种超宽带桥T型模拟线性化器,对其进行了详细的理论分析和模型仿真。该模拟线性化器的核心电路由T型衰减器和PIN二极管构成,可以实现幅度扩张和相位压缩,具有偏置电路简单、输入输出端口驻波良好等优点。结合理论分析和仿真设计,设计制作的0.8~2 GHz桥T型模拟线性化器能够实现幅度扩张约5 dB,相位压缩18°。This paper presents the design of an ultra-broadband T-type analog linearizer with detailed analysis and simulation. The proposed structure, which is mainly composed of tee-attenuator and PIN diode, can achieve the amplitude expansion and phase compression. Featuring a simple bias circuit and good return loss of both two ports, the designed linearizer operates in the 0.8 GHz to 2 GHz frequency range. The test results confirm that5 dB amplitude expansion and 18°phase compression can be achieved respectively in this way.
