Abstract:
A power amplifier apparatus supporting reverse intermodulation product (rIMD) cancellation is provided. The power amplifier apparatus includes an amplifier circuit configured to amplify and output a radio frequency (RF) signal for transmission via an antenna port. The antenna port may receive a reverse interference signal, which may interfere with the RF signal to create a rIMD(s) that can fall within an RF receive band(s). A reverse coupling circuit is provided in the power amplifier apparatus to generate an interference cancellation signal based on the reverse interference signal. The amplifier circuit is configured to amplify the interference cancellation signal and the RF signal to create an intermodulation product(s) to suppress the rIMD(s) to a determined threshold. By suppressing the rIMD(s) in the power amplifier apparatus, it is possible to support concurrent transmissions and receptions in a number of RF spectrums while in compliance with stringent regulatory spurious emissions (SEM) requirements.

Claim (Index 20):
A power amplifier apparatus comprising:\n an antenna port coupled to at least one antenna; an amplifier circuit comprising an amplifier input and an amplifier output, the amplifier circuit configured to amplify a radio frequency (RF) signal received via the amplifier input and provide the RF signal to the antenna port via the amplifier output; and a reverse coupling circuit provided in parallel to the amplifier circuit between the antenna port and the amplifier input, the reverse coupling circuit configured to generate and provide an interference cancellation signal to the amplifier input; wherein the amplifier circuit is further configured to generate at least one intermodulation product (IMD) at the amplifier output based on the interference cancellation signal to suppress at least one reverse intermodulation product (rIMD) to a defined threshold.
