Abstract
Systems, devices, and methods related to time-interleaved polyphase linearization for a receive signal chain are provided. An example receive signal chain includes an input node to receive a radio frequency (RF) signal. The receive signal chain further includes a plurality of polyphase mixer circuitries including first mixers and first local oscillators to generate a plurality of phase-shifted downconverted signals based on the received RF signal. The receive signal chain further includes a first multiplexer to select one of the plurality of phase-shifted downconverted signals during each time slot of a plurality of time slots. The receive signal chain further includes signal conditioning circuitry comprising at least one nonlinear component. The signal conditioning circuitry conditions, during each time slot, a respective selected one of the plurality of phase-shifted downconverted signals to generate a conditioned signal. The receive signal chain further includes analog-to-digital-converter (ADC) downstream of the signal conditioning circuitry.
