BALANCED-TO-UNBALANCED (BALUN) TRANSFORMER

The invention relates to a balanced-to-unbalanced (balun) transformer which may include two metal layers on a substrate, a first winding following a first winding path, and a second winding followinga second winding path, where each winding is formed in one or more of the two metal layers. The winding paths may include winding segments each disposed around a central axis of the balun transformer,where connectors join adjacent winding segments such that the winding paths are continuous between ends of the windings. The second winding path may be interwoven with, but independent from, the first winding path to form a resultant pattern that is substantially symmetrical. The second winding may include a number, n, of sub-windings, where n > 1 such that a resultant number of winding segmentsof the second winding is greater than a resultant number of winding segments of the first winding by a factor of n. 本公开涉及一种平衡-不平衡变压器。平衡-不平衡(换衡器)变压器可以包括在基底上的两个金属层、在第一绕组路径之后的第一绕组以及在第二绕组路径之后的第二绕组，其中每个绕组形成在两个金属层中的一个或多个中。绕组路径可以包括绕组段
