Abstract: A radio frequency front end system has a first receive path with a first receive filter and is configured to receive a first receive signal in a first band group from a first antenna. A first additional receive path is configured to receive a radio frequency signal from the first antenna unfiltered. A first switch is configured to couple the first antenna to either the first receive path or the first additional receive path to bypass the first receive filter.

Abstract: Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a method of coexistence management includes generating an RF observation signal based on observing a cellular transmit signal using a cellular front end system, processing the RF observation signal to generate digital observation data using a cellular transceiver, generating a digital wireless local area network (WLAN) receive signal based on processing an RF WLAN receive signal using a WLAN transceiver, compensating the digital baseband WLAN receive signal for RF signal leakage based on the digital observation data using a discrete time cancellation circuit of the WLAN transceiver.

Abstract: Radio frequency front-end systems with filter reuse. In certain embodiments, a front-end system includes a filter, a low noise amplifier (LNA), and a switch interposed between the filter and an input to the LNA. In a first state of the switch, the filter serves to filter a radio frequency signal that is amplified by the LNA. The front-end system further includes a power amplifier that is coupled to the switch. Additionally, in a second state of the switch, the filter serves to filter an amplified radio frequency transmit signal provided by the power amplifier. Accordingly, a filter along a receive path of the front-end system is reused for transmit.

Abstract: Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a method of coexistence management in a mobile device includes processing an RF receive signal to generate a digital baseband receive signal using a receive channel of a first transceiver, processing a first RF observation signal to generate a first digital observation signal using a first observation channel of the first transceiver, generating spectral regrowth observation data based on processing process the first digital observation signal using a first spectral regrowth baseband sampling circuit of the first transceiver, and compensating the digital baseband receive signal for RF signal leakage based on the spectral regrowth observation data and on direct transmit leakage observation data using a discrete time cancellation circuit of the first transceiver.

Abstract: The radio frequency front-end systems herein include modules having bandwidth controllable components, such as amplifier and filters. By implementing the modules with bandwidth control, the same module can be used for operation of multiple frequency bands including a first frequency band and a second frequency band. Thus, when implementing features such as carrier aggregation, multiple-input multiple-output (MIMO), and/or sounding resource signaling (SRS) for supporting the multiple frequency bands, the total number of modules used can be reduced and/or additional feature support can be provided compared to an implementation in which each module supports a single frequency band.
