摘要

本文提出了一种D波段移相器，它利用一位倒相器（PI），然后是两个级联的反射型移相器（RTPS）。PI使用两个相同的共源共栅放大器和一个三轴巴伦，以实现紧凑的形状因子，并在两种状态下提供相同的负载。RTPS由于其固有的高Q和调谐范围而使用SiGe PIN二极管作为其谐振负载。移相器在90 nm SiGe BiCMOS技术平台上实现，在360°相移范围内，频率高达145 GHz时，插入损耗小于5.5 dB。通过使用双电压控制，通过选择适当的点，插入损耗变化保持在±0.9 dB以内。这种移相器在宽频带上工作时，在插入损耗、功耗和幅度误差方面实现了有竞争力的性能。

A D-Band Reflective-Type Phase Shifter Using a SiGe PIN Diode Resonant Load

This work presents a D-band phase shifter which utilizes a one-bit phase inverter (PI), followed by two cascaded reflective-type phase shifters (RTPSs). The PI uses two identical cascode amplifiers and a triaxial balun for compact form factor and to provide identical loading in both states. The RTPSs use SiGe PIN diodes for their resonant loads due to their naturally high-Q and tuning range. The phase shifter is implemented in a 90-nm SiGe BiCMOS technology platform, and achieves insertion loss < 5.5 dB with a 360° phase shift range, for frequencies up to 145 GHz. By using dual voltage control, the insertion loss variation is kept within ±0.9 dB by selecting the appropriate points. This phase shifter achieves competitive performance in terms of insertion loss, power consumption, and amplitude error while operating over a wide bandwidth.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
