Abstract:
A radio frequency front end (RFFE) is configured to support dual connectivity communications, in which two different radio access technologies such as LTE and NR are used simultaneously for uplink communications from a wireless communications device to a base station. The RFFE has two channels and two respectively associated antennas. The first channel transmits an NR signal from the first antenna. The second channel transmits an LTE signal from the second antenna. For reception, the first channel produces a main NR receive signal and LTE diversity signal. The second channel produces a main LTE receive signal and an NR diversity signal.

Claim (Index 1):
A radio frequency (RF) front end, comprising:\n a first power amplifier that amplifies a first RF transmit signal to create a first amplified RF transmit signal for transmission by a first antenna, wherein the first RF transmit signal represents data in accordance with a first radio access technology; a second power amplifier that amplifies a second RF transmit signal to create a second amplified RF transmit signal for transmission by a second antenna concurrently with the transmission of the first RF transmit signal by the first antenna, wherein the second RF transmit signal represents data in accordance with a second radio access technology; a first signal amplifier that amplifies a first RF receive signal from the first antenna to create a first amplified RF receive signal; a first signal splitter that processes the first RF receive signal to produce a first main RF signal and a first diversity RF signal, wherein the first main RF signal represents data in accordance with the first radio access technology and the first diversity RF signal represents data in accordance with the second radio access technology; a second signal amplifier that amplifies a second RF receive signal from the second antenna to create a second amplified RF receive signal; and a second signal splitter that processes the second amplified RF receive signal to produce a second main RF signal and a second diversity RF signal, wherein the second main RF signal represents data in accordance with the second radio access technology and the second diversity RF signal represents data in accordance with the first radio access technology.
