Stripline quadrature coupler

摘要: STRIPLINE QUADRATURE COUPLER ABSTRACT The coupler accepts four independent RF input signals, divides each-input into equal parts, and applies each part to one of adjoining output ports. Each signal divided is phase shifted a multiple 90°whereby the ports, taken in proper order, are quadrature. novel comprises hybrid couplers, all which fabricated on dielectric substrate. couplers located substrate unique interleaved configuration whereby intercouplings formed between selected couplers. construction results electrical length being controlled and, preferably, same length.
