Abstract

We have derived a lumped-element circuit from its coupled line counterpart for a 90/spl deg/, 3dB hybrid coupler. We discuss the uses, design, and characteristics of such circuits in CMOS technology. We show measured characteristics of an example 50/spl Omega/, 2GHz coupler with 65dB of image rejection, 18dB of directivity and a 4.7dB noise figure.
采用CMOS技术实现的2GHz正交混合电路
我们从90/spl度/ 3dB混合耦合器的耦合线对应物中导出了集总元件电路。我们讨论了这种电路在CMOS技术中的用途、设计和特点。我们展示了一个50/spl ω / 2GHz耦合器的测量特性,该耦合器具有65dB的图像抑制,18dB的指向性和4.7dB的噪声系数。
