Abstract:
A communications device may include a first transmit path having a first band pass filter operating at a first frequency band having a first bandwidth, and a second transmit path having a second band pass filter operating at a second frequency band having a second bandwidth. The second frequency band may be adjacent the first frequency band and the second bandwidth may be less than the first bandwidth. The communications device may include a third receive path operating at a third frequency band having a third bandwidth, and a fourth receive path operating at a fourth frequency band having a fourth bandwidth. The fourth frequency band may be adjacent the third frequency band, and the fourth bandwidth may be less than the third bandwidth.
