本文提出了一种H波段矢量调制器,它是针对移相应用而优化的。该矢量调制器采用基于功率分配器、平衡-不平衡变换器和可变增益放大器的紧凑拓扑结构实现,在235至270 GHz之间的频率范围内具有最先进的性能,RMS增益和相位误差非常低。在此频率范围内,可实现完整的360°相位控制范围,插入损耗小于6.5 dB。该MMIC采用50 nm GaAs mHEMT工艺,芯片尺寸仅为1.25mm × 1.00mm。
This paper presents a H-Band vector modulator which is optimized for phase shifting applications. The vector modulator is realized using a compact topology based on power dividers, baluns and variable gain amplifiers and shows state-of-the-art performance for frequencies between 235 and 270GHz with very low RMS gain and phase errors. In this frequency range the full 360° phase control range is achieved with less than 6.5 dB insertion loss. The MMIC was fabricated using a 50nm GaAs mHEMT technology and the resulting chip-size is only 1.25mm × 1.00 mm.
