Abstract: Disclosed is a method and compounds useful for performing said method for simultaneous synthesis of a plurality of oligonucleotide molecules, and more specifically for orthogonal synthesis of at least two different oligonucleotide molecules at the same time with applications in combinatorial chemistry and DNA encoded libraries (DEL).

Abstract: A multi-beam antenna array includes a receiver multi-layer circuit card assembly (CCA) comprising of a first plurality of monolithic microwave integrated circuits (MMICs), a first plurality of radiating elements, and a first plurality of interconnections; a transmitter multi-layer CCA comprising of a second plurality of MMICs, a second plurality of radiating elements, and a second plurality of interconnections; and a single aperture shared by the receiver multi-layer CCA and the transmitter multi-layer CCA, where each of the first and second plurality of MMICs includes mixed analog and digital circuits surface mounted onto said each MMIC.
