We present an RF-photonic phased-array receiver that provides simultaneous multi-band and multi-beam operation in the millimeter-wave region of the spectrum. It uses a photonic integrated circuit to perform RF beamforming with near unlimited beam-ban

We present the first demonstration of a tightly coupled array (TCA) excited by high-power photodiodes directly integrated onto the antenna substrate. As a complex electrical feed network is not required to feed the radiating elements, the design can

Since their conception in the early 1900s, radar systems have mostly used a single RF beam to probe the environment in search of objects of interest. Traditionally, this is accomplished by scanning the beam over a defined region and using time of fli

In this paper, we packaged a multichip module (MCM) in multilayer liquid crystal polymer (LCP) substrate using V-shaped wire bond and 3-D-printed housing. In the proposed module, two low-noise amplifiers (LNAs) are cascaded in series to obtain high g
