Abstract: A shared-duplexer front end architecture is configured for operation in either of the 5G new radio n1 band or n65 band, while maintaining low spurious emissions in the adjacent n34 band. A front end module can have a first RF signal processing circuit for receiving RF signals from an antenna, and a second RF signal processing circuit for amplifying and transmitting RF signals via the antenna. The first RF signal processing circuit can be connected to the second RF signal processing circuit via a bypass filter circuit configured to short RF noise (particularly signal components within the n34 band) to the first RF signal processing circuit. The bypass filter circuit can be selectively enabled during transmission by the second RF signal processing circuit to effectively eliminate noise components of the RF signal and reduce spurious emissions in the n34 band.

Abstract: Envelope tracking systems with modeling for power amplifier supply voltage filtering are provided herein. In certain embodiments, an envelope tracking system includes a supply voltage filter, a power amplifier that receives a power amplifier supply voltage through the supply voltage filter, and an envelope tracker that generates the power amplifier supply voltage. The power amplifier provides amplification to a radio frequency (RF) signal that is generated based on digital signal data, and the envelope tracker generates the power amplifier supply voltage based on an envelope signal corresponding to an envelope of the RF signal. The envelope tracking system further includes digital modeling circuitry that models the supply voltage filter and operates to digitally compensate the digital signal data for effects of the supply voltage filter, such as distortion.
