Maxim MAX2032高线性上下变换混频方案
Maxim 公司的MAX2032是高线性无源上/下变换混频器, 从650MHz 到1000MHz,可提供+33dBm IIP3, 7dB NF以及7dB转换损耗.本地振荡(LO)的频率范围从650MHz 到 1250MHz,IF频率从DC到250Mz,输入1dB压缩点为24dBm,集成了LO缓冲器和RF以及LO平衡/不平衡回路,LO驱动从-3dBm到+3dBm,主要用在WCDMA/LTE以及cdma2000基站, GSM 850/GSM 900 2G 和2.5G EDGE基站,WiMAX基站和CPE,无线本地回路(WLL),微波和固定宽带接入以及数字和扩展频谱通信系统.本文介绍了MAX2032主要特性,方框图以及典型应用电路.
The MAX2032 high-linearity passive upconverter or downconverter mixer is designed to provide +33dBm IIP3, 7dB NF, and 7dB conversion loss for a 650MHz to 1000MHz RF frequency range to support a multitude of base-station applications. With a 650MHz to 1250MHz LO frequency range, this particular mixer is ideal for high-side LO injection architectures. For a pin-to-pincompatible mixer meant for low-side LO injection, refer to the MAX2029.
