Abstract
A radio frequency circuit assembly architecture is disclosed. An example radio frequency circuit assembly architecture comprises a signal contact and an antenna contact, a power amplifier module connected in a signal path between the signal contact and the antenna contact, the signal path between the power amplifier module and the antenna contact including a differentially signaled portion having a first path and a second path, and a pair of band pass filters, a first band pass filter of the pair of band pass filters being connected in the first path of the differentially signaled portion and a second band pass filter of the pair of band pass filters being connected in the second path of the differentially signaled portion.
