15020 基于130 nm RF CMOS工艺,提出了一种可实现上/下双向变频功能的K波段有源混频器。 An active bidirectional mixer performing the up/down conversion is proposed at K-band with a 130 nm CMOS in this paper.
15021 当收发机工作于接收模式时,双向混频器执行下变频功能,将低噪放大器放大后的射频信号转换为中频信号。 The mixer performs the down conversion in the Rx mode and converts the radio frequency(RF) signal amplified by low noise amplifier(LNA) into the intermediate frequency(IF) signal,
