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 24 to 30-GHz Phased Array Transceiver Front End With 2.8 to 3.1-dB RX NF and 22 to 24% TX Peak Efficiency

A 24 to 30-GHz Phased Array Transceiver Front End With 2.8 to 3.1-dB RX NF and 22 to 24% TX Peak Efficiency 150 150

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 …
