  • Reducing intermodulation distortion for intra-band dual connectivity
    Patent number: 11218286
    Abstract: A radio frequency front end (RFFE) is configured to support dual connectivity communications, in which two different radio access technologies such as 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) data connections are used simultaneously for communications between a wireless communication device and respective LTE and NR base stations. In described embodiments, the RFFE uses two power amplifiers to reduce intermodulation distortion (IMD). The two power amplifiers produce output signals for a 4G LTE uplink and a 5G NR uplink, respectively. The RFFE also has a combiner that mixes the output signals to produce a composite output signal representing both LTE and NR data. Bypass switches may be used to configure the RFFE so that it can be used for single conventional 4G LTE communications.
