The need for unrestricted, high-quality, and high-speed communications in planned sixth
generation (6G) wireless systems drives the development and research towards the sub …

This article presents a 205–273-GHz wideband frequency multiplier chain (FMC) in a 0.13-
SiGe BiCMOS technology with/500 GHz. The proposed FMC consists of a-band input …

A sub-THz (88–136 GHz) full-duplex (FD) phased-array transceiver (TRX) integrating an RF
self-interference (SI) canceller with differential feeding FD antennas is presented in this …

This article presents a fully integrated direct-digital 16-quadrature amplitude modulation
(QAM) communication link operating at 135 GHz. The transmitter employs a Cartesian direct …

We present an integrated frequency multiplier-by-six (sextupler) for signal generation at-
band (220–325 GHz) frequencies. Typically, multiplication-by-six in state-of-the-art designs …

Terahertz (THz) carrier frequencies (100 GHz to 10 THz) have been touted as a source for
unprecedented wireless connectivity and high-precision sensing, courtesy of their wide …

Mankind is currently living in the era of mobile communication. Mobile communication
encompasses almost all areas of our daily life and is heavily used in most sectors of …

This paper presents an array of four Vivaldi antennas, a 1-to-4 power divider for feeding, and
a transition structure to a WR-3 waveguide. The power divider is based on substrate …

The free-space wavelengths in the 300-GHz band are so short that it is extremely
challenging to realize phased arrays with a half-wave antenna pitch, required for preventing …

This manuscript introduces an integrated power amplifier (PA) meticulously designed for the
D-band, addressing the interconnect challenges between power amplifiers and transmitting …
