Abstract:

This article presents K/Ka-band four-element four-beam phased-array transmitter (TX) and receiver (RX) front-ends. Hybrid-packaged technology is employed, consisting of one TX/RX 65-nm CMOS beamformer and four 0.1- $mu$ m GaAs power amplifiers (PAs)/low-noise amplifiers (LNAs). Each beam maintains a full connection to every antenna element without degrading …

Author(s): Wooram Lee, Caglar Ozdag, Jean-Olivier Plouchart, Alberto Valdes-Garcia, Bodhisatwa Sadhu

Abstract:

This article presents a compact 24–30-GHz phased array transceiver (TRX) front end (FE) with high transmitter (TX) power efficiency and low receiver (RX) noise figure (NF) in a 130-nm bipolar CMOS (BiCMOS) technology supporting different 5th generation mobile network (5G) frequency range 2 (FR2) bands (n257, n258, and n261). We introduce …

A 4-Element Ka-Band Phased-Array Receiver With Code-Domain Hybrid Beamforming
A 4-Element Ka-Band Phased-Array Receiver With Code-Domain Hybrid Beamforming 150 150
Author(s): Ziyi Lin, Haikun Jia, Chuanming Zhu, Wei Deng, Huabing Liao, Bao Shi, Lujie Hao, Xiangrong Huang, Baoyong Chi

Abstract:

This letter presents a 4-element phased-array receiver with code-domain hybrid beamforming (CDHBF) in 65-nm CMOS technology. Code-division multiplexing is used to fully preserve the flexibility in the digital domain while using a single RF interface, which reduces the RF chain complexity, reduces the chip area, and improves power efficiency. Phase …
