Abstract

This paper presents the design of a pseudomorphic high electron mobility transistor (pHEMT) self-oscillating mixer (SOM) for millimeter wave wireless communication systems. The 180° out-of-phase technique is chosen to both improve the desired lower sideband (LSB) signal and to achieve a satisfactory rejection of the unwanted signals (LO, USB and IF). This SOM is designed on the PH15 process of UMS foundry which is based on 0.15 µm GaAs pHEMT. The signal is up-converted from 2 GHz-IF frequency to 26 GHz-LSB frequency, using an autogenerated 28 GHz-LO signal. Simulations were performed using the advanced design system (ADS) workflow. They show 6.4 dB conversion gain and a signal rejection rate of 29.7 dB for the unwanted USB signal. the chip size is 3.6 mm2.

用于第五代通信的高阻自激振荡上变频混频器

本文介绍了一种用于毫米波无线通信系统的伪高电子迁移率晶体管（pHEMT）自激混频器（SOM）的设计。选择180°异相技术是为了改善所需的下边带（LSB）信号，并实现对不需要的信号（LO、USB和IF）的满意抑制。该SOM是根据UMS铸造厂的PH15工艺设计的，该工艺基于0.15µm GaAs pHEMT。该信号使用自动生成的28 GHz LO信号从2 GHz IF频率上变频到26 GHz LSB频率。使用高级设计系统（ADS）工作流程进行仿真。它们显示出6.4dB的转换增益和29.7dB的不需要的USB信号的信号抑制率。芯片尺寸为3.6mm2。
