Apple patents circuitry to reduce signal distortion in wireless chips

Patent drawing from the official filing.

This filing describes a design for wireless amplifier circuitry that includes specific components to reduce non-linear behavior in transistors and inductors. It uses auxiliary transistors and filters to suppress intermodulation distortion, which can occur when signals are amplified.

Why it mattersIt improves the quality of radio frequency signal processing in electronic devices by reducing distortion during amplification.

In the filing’s own words

An electronic device may include wireless circuitry with a processor, a transceiver circuit, a front-end module, and an antenna. The front-end module may include amplifier circuitry such as a low noise amplifier for amplifying received radio-frequency signals. The amplifier circuitry may include non-linearity suppression circuitry that suppresses or reduces non-linear behavior of components such as a core amplification transistor and a degeneration inductor within the amplifier circuitry. The non-linearity suppression circuitry may include an intermodulation distortion suppression circuit having an auxiliary amplification transistor. The non-linearity suppression circuitry may include a frequency-selective filter coupled to the degeneration inductor.
