Radio frequency communication circuits and methods

Abstract

An apparatus may include: a common input terminal; a first inductor and a second inductor, each coupled to the common input terminal, wherein the first inductor and the second inductor are disposed in an electromagnetic coupling configuration; a lower frequency band output terminal coupled to the first inductor; a higher frequency band output terminal coupled to the second inductor; wherein the first inductor and the second inductor are to separate signals received from the common input terminal into the lower and the higher frequency band output terminals based on frequencies of the received signals. An apparatus may include: a first transformer magnetically couple a signal within a first frequency band and generate a first magnetic field with a first orientation; and a second transformer configured to magnetically couple a signal within a second frequency band that is different from the first frequency band.
