A true time-delay-based bandpass multi-beam matrix at mm-Waves is introduced that is suitable for applications with instantaneously wide bandwidth signals and for MIMO systems. A 0.13 ¿m SiGe BiCMOS chip prototype covers the 30-to-40 GHz frequency range instantaneously and supports 6 channels while producing 7 simultaneous beams with 18° spatial resolution and ±54° of spatial coverage.
