论文摘要
提出了使用新颖的数字波束形成阵列的25-40GHz被动式搅拌器优先接收器。该体系结构使用一种新型技术来使用接收器和匹配网络中混合器的抗性来阻抗匹配。混合器的小开关电阻可以使用匹配网络匹配到天线。讨论了几个匹配网络，包括用于宽带应用程序的可调匹配网络。该设计实现了低于8dB的噪声图，转化率增长率为18dB，IIP3在25-40GHz的频率范围内约为 +4dBm。原型芯片是在28nm散装CMOS工艺中制造的。
A 25-40GHz passive mixer-first receiver using a novel architecture for digital beamforming arrays is proposed. The architecture uses a novel technique for impedance matching using the on-resistance of the mixers in the receiver and matching networks. The small switch resistance of the mixers can be matched to the antenna using matching networks. Several matching networks are discussed, including a tunable matching network for wideband applications. The design achieves a noise figure that is lower than 8dB, a conversion gain of 18dB, and an IIP3 of around +4dBm across the frequency range of 25-40GHz. A prototype chip is fabricated in 28nm bulk CMOS process.
