A double-balanced ring mixer is provided in the form of a microwave integrated circuit that has a homogeneous, multilayer structure. The mixer utilizes baluns comprising rectangular coaxial transmission lines that are capable of operating over a wide range of frequencies while taking up little space. A typical implementation operates at frequencies from approximately 0.9 to 6 GHz, although other frequencies, such as approximately 0.1 to 10 GHz, are achievable.
