K/Ka-Band Hybrid-Packaged Four-Element Four-Beam Phased-Array Transmitter and Receiver Front-Ends With Optimized Beamforming Passive Networks

K/Ka-Band Hybrid-Packaged Four-Element Four-Beam Phased-Array Transmitter and Receiver Front-Ends With Optimized Beamforming Passive Networks 150 150

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 …

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

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 …
