Author(s): Xiaguang Li, Qing Miao, Shiheng Yang, Tianting Zhao, Sijun Du, Xiaoyang Zeng, Zhiyuan Chen

Abstract:

This article presents a globally optimized radio frequency (RF) energy harvesting system that leverages the novel concepts of 3-D maximum power point tracking (3-D MPPT) and collaborative source reconfiguration to achieve high MPPT accuracy and a wide input power range. The proposed 3-D MPPT coordinates the energy sources, optimizes the …

A Compact Reconfigurable Dual-Path Dual-Band LNA for 5G NR FR2 Applications

A Compact Reconfigurable Dual-Path Dual-Band LNA for 5G NR FR2 Applications 150 150
Author(s): Pei Qin, Junyu Wu, Taotao Xu, Yongchun Li, Wenjie Feng, Quan Xue, Wenquan Che

Abstract:

This article presents a reconfigurable dual-path dual-band low noise amplifier (LNA) for fifth generation (5G) millimeter-wave (mmW) communications. A novel band-switching input matching architecture based on the cross-connected transistors is proposed to achieve optimal dual-band input matching and $g_{m}$ -boosting. This architecture allows the dual-band input transistors to share …

A Simultaneous Dual-Carrier Transformer-Coupled Passive Mixer-First Receiver Front-End Supporting Blocker Suppression

A Simultaneous Dual-Carrier Transformer-Coupled Passive Mixer-First Receiver Front-End Supporting Blocker Suppression 150 150
Author(s): Jamie C. Ye, Alain H. Antón, Sanaz Sadeghi, Russ H. Huang, Alyosha C. Molnar

Abstract:

A high dynamic range N-path passive mixer-first receiver architecture capable of simultaneously down-converting two arbitrary bands through a single RF port is presented. The architecture consists of two passive mixers arranged in a series configuration with a transformer front-end to minimize cross-loading between mixers while still providing impedance transparency and …
