Phased-Array-Fed Lenses (PAFLs) are a promising low-power alternative to Phased Array Antennas (PAAs) through the use of a lens aperture and activating sub-arrays of its full feed array. While PAFL be...
A fully integrated multi-standard digital transmitter featuring linearity enhancement is demonstrated, incorporating a reconfigurable digital modulator to support OOK/BPSK/QPSK/16-QAM multi-modulation...
The talk provides a comprehensive review of fundamental SiGe BiCMOS building blocks for D-band transceivers. Design strategies are explored to enhance performance in terms of wideband amplification an...
This paper presents a 38-41 GHz direct-conversion I/Q transmitter in 0.12-μm GaN technology that achieves high linearity and low error-vector-magnitude (EVM) for high-order 4096-QAM modulation. The pr...
Where space and weight become tough requirements and performance drives the relevance of using waveguide systems with low insertion loss and potential to realize challenging beam patterns, a restricti...
This paper presents an ultra-compact and broadband fully-differential rat-race coupler in 180-nm CMOS process, utilizing a novel folded inverted coupled-line (FICL) structure. By tuning the coupling c...
