A K/Ka-Band Transmit/Receive Front-End With Triple-Coupled Transformer Technique in 65-nm Bulk CMOS

A K/Ka-Band Transmit/Receive Front-End With Triple-Coupled Transformer Technique in 65-nm Bulk CMOS 150 150

Abstract:

This article presents a K/Ka-band transmit/receive (T/R) front-end for jointed sensing and communication (JSAC) applications. A reconfigurable matching network for both signal reception and transmission is realized using the proposed triple-coupled transformer (TCT) technique, achieving low power loss and a compact footprint. The T/R switch at …

Analysis and Design of Power Amplifier Using Parallel-Combined Multisegment Transformer

Analysis and Design of Power Amplifier Using Parallel-Combined Multisegment Transformer 150 150

Abstract:

This letter presents a highly efficient power amplifier (PA) using a parallel-combined vertical multisegment transformer for 5G new radio (NR) applications operating in bands n257 and n258, in a 65-nm bulk CMOS process. A multisegment transformer facilitates a lower provided input impedance than a conventional transformer, enabling the PA to …

A Broadband and Compact GaN Millimeter-Wave MMIC SPDT Switch Using Modified π-Networks

A Broadband and Compact GaN Millimeter-Wave MMIC SPDT Switch Using Modified π-Networks 150 150

Abstract:

This letter presents a design methodology for broadband and compact millimeter-wave (mm-wave) single-pole double-throw (SPDT) switches targeting the Ku–Ka band. Conventional SPDT switches based on quarter-wavelength transmission line typically occupy significant chip area, while alternative designs utilizing standard $\pi $ -type equivalent circuits often suffer from bandwidth degradation due to …
