摘要
提出了一种适用于v波段行波管功率放大器的模拟预失真(APD)线性化器。采用了一种基于肖特基势垒二极管(SBD)三维电磁仿真模型(3D EM model)的新型“场路组合”设计方法。研制并测试了一种由90°波导3dB混合波导和两个sbd组成的反射型APD线性器。实际测量结果表明，在- 25$\sim$10dBm的输入功率范围内，增益扩展大于7。在59.1$\sim$61.1GHz频段，相位扩展超过28°。
A V-Band Diode-Based Analog Predistortion Linearizer for Traveling Wave Tube Amplifiers
This paper presents an analog predistortion (APD) linearizer suitable for V-band traveling wave tube power amplifier. A new “field-circuit combination” design method based on the Schottky barrier diode (SBD) three-dimensional electromagnetic simulation model (3D EM Model) is used. A reflection type APD linearizer consisting of a 90° waveguide 3dB hybrid and two SBDs is developed and tested. The actual measurement results show that within the input power range of- 25$\sim$10dBm, the gain expansion is more than 7. 8dB and the phase expansion is over 28° in the frequency band 59.1$\sim$61.1GHz.
