Abstract: This paper presents a 2.4GHz two-layer $4\times 4$ Butler matrix in microstrip technology. By integrating several wideband building blocks, i.e., slot-coupled quadrature hybrids, ...
Abstract: A 4 × 4 crosspoint switch circuit based on resonant elements is demonstrated on a generic InP integrated photonics platform. The switch matrix is constructed from a crosspoint grid of the ...
