Abstract
An apparatus and method for allowing two different signal paths to be coupled to a multi-tap transformer balun. The multi-tap transformer has a first port, which is coupled to a single antenna, and two or more differential secondary ports. Each port has one or more taps, which are optimized separately for each of the signal paths, allowing each of the two or more signal paths to operate in different frequency bands. Use of the method of the invention can decrease the number of external components and integrated circuit package pins, and reduce the area required for each signal path on an integrated circuit die, a printed circuit board, or the like.
