Abstract

This letter presents a low-cost third-harmonic mixer suitable for ${W}$ -band retrodirective systems. Measured results show that when fixing the local oscillator (LO) frequency at 35 GHz, the conversion loss (CL) below 11 dB is achieved over the radio frequency (RF) range of 100–110 GHz with intermediate frequency (IF) from dc to 5 GHz, while for the RF range of 108 GHz, the minimum CL of 6.8 dB is obtained. Therefore, the presented mixer exhibits an excellent performance with low CL in comparison with that of a normal subharmonic mixer (SHM). The isolations of RF/LO and RF/IF are improved to the level of 35 and 38 dB, respectively. The simulated and measured isolations of LO/RF are 41 and 37 dB, respectively. This mixer has properties of low LO frequencies, high isolations, and low CL; therefore, it provides a high-performance and low-cost alternative solution for the applications of retrodirective systems.

用于频带反向系统的低成本三次谐波混频器

本文介绍了一种适用于${W}$波段反向指令系统的低成本三谐波混频器。测量结果表明，当本振(LO)频率固定在35 GHz时，在100-110 GHz的射频(RF)范围内，直流到5 GHz的中频(IF)范围内，转换损耗(CL)低于11 dB，而在108 GHz的射频范围内，最小的CL为6.8 dB。因此，与普通的亚谐波混频器(SHM)相比，该混频器具有低CL的优异性能。RF/LO和RF/IF的隔离度分别提高到35 dB和38 dB。模拟和测量的LO/RF隔离度分别为41和37 dB。该混频器具有低LO频率、高隔离和低CL的特性;因此，它为逆向指令系统的应用提供了一种高性能和低成本的替代解决方案。

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.
