摘要

本文对高图像抑制的上或下转换器进行了综述。下一代卫星应用需要高上行和下行速度，因此具有低图像抑制比的宽带设计非常重要。本文采用$0.18\ {\mu}\mathbf{m}$ CMOS单正交结构，设计了一个28-30GHz上变频器，低中频范围为1.2 GHz, IRR <-38 dBc。本文还介绍了一种17-21 GHz的下变频器，其低中频范围为2.2 GHz, IRR <-40 dBc。

Reviews of High Image Rejection Up and Down Converters for Next-Generation Satellite Applications

In this paper, a review of high image rejection up-or down-converters is presented. Next-generation satellite applications need high uplink and downlink speeds, so a broadband design with a low image rejection ratio is important. By using a $0.18\ {\mu}\mathbf{m}$ CMOS single-quadrature architecture, this paper presents a 28-30GHz up-converter with a low-IF frequency range of 1.2 GHz and an IRR of <-38 dBc. Also presented is a 17-21 GHz down-converter with a low-IF frequency range of 2.2 GHz and a <-40 dBc IRR.
