Abstract:
1. A Lange coupler comprising: input and through conductor strips coupled respectively to input and through ports of the Lange coupler, a central conductor strip, with the input and through conductor strips on opposite sides of the central conductor strip thereby defining a pair of outer conductors, with one end of the input conductor strip connected to one end of the central conductor strip and with one end of the through conductor strip connected to another end of the central conductor strip, wherein the central conductor strip is also connected to other ends of the input and through conductor strips at a midpoint along its length; an unbroken peripheral ground conductor surrounding the input and through conductor strips, the peripheral ground conductor and input and through conductor strips being arranged on a first metal layer; first and second ground conductor strips coupled to the peripheral ground conductor at each end and interposed between the central conductor strip and a respective one of the pair of outer conductors; and coupled and isolated conductor strips arranged on a second metal layer, arranged on opposite lateral sides of the central conductor strip.
