Abstract: An electronic device may include an antenna, a transceiver, and a low noise amplifier module that amplifies receive signals from the antenna to the transceiver circuitry in a first configuration and passes transmit signals from the transceiver to the antenna in a second configuration. The low noise amplifier module may include a first switching circuit coupled to the antenna, a second switching circuit coupled to the transceiver, at least one low noise amplifier coupled between the first and second switching circuits, and a transmit bypass path coupled between the first and second switching circuits. The transceiver may be located in a first electronic device region, whereas the low noise amplifier module and the antenna may be located in a second region. The low noise amplifier module may help compensate for signal loss between the first and second regions and allow for transmit signals to pass to the antenna.

Abstract: An electronic device may include a radio-frequency front end (RFFE) module coupled to antenna(s). The module may have a power amplifier, a transmit switch, a receive switch, low noise amplifiers, and an antenna switch. The transmit switch may be coupled to the antenna switch over transmit paths. The antenna switch may be coupled to the low noise amplifiers over receive paths. Filters on different transmit paths may have passbands overlapping the transmit bands of respective first and second frequency bands. A filter on the receive path may have a passband overlapping the receive bands of the first and second frequency bands. The antenna switch may have multiple throws for concurrently coupling one of the transmit paths and one of the receive paths to the antenna(s). Combining filters and switching in this way may minimize the number of low noise amplifiers and filters on the module without sacrificing performance.

Abstract: In an electronic device, a transmitter and a receiver may each be coupled to one or more antennas to enable the electronic device to both transmit and receive wireless signals. The electronic device may include two or more antennas coupled to a radio frequency front end module that receives different downlink signals on different frequency bands. For example, a switch may couple a first antenna to a first duplexer to support transmitting and/or receiving signals within a first frequency band and a second antenna to a second duplexer to support transmitting and/or receiving signals within a second frequency band. As such, the electronic device may concurrently transmit and/or receive two signals having different frequencies, which may improve downlink throughput and/or support downlink carrier aggregation.

Abstract: An electronic device can include a first group of radio-frequency amplifiers coupled to one or more first antenna(s) disposed at a first end of the device, a second group of radio-frequency amplifiers coupled to one or more second antenna(s) disposed at a second opposing end of the device, a first envelope tracking integrated circuit (ETIC) coupled to the first group of radio-frequency amplifiers, and a second envelope tracking integrated circuit (ETIC) coupled to the second group of radio-frequency amplifiers. The first and second ETICs can be coupled together via a bidirectional input-output voltage path and a feedback voltage path. At least the first ETIC can include a first envelope tracking amplifier, a second envelope tracking amplifier, a voltage converter coupled to an output of the first envelope tracking amplifier, and a feedback controller coupled to an output of the second envelope tracking amplifier and configured to adjust the voltage converter.
