Abstract: Aspects of this disclosure relate to a segmented receiver for a wireless communication system. The segmented receiver includes a first receiver segment and a second receiver segment configured to receive respective radio frequency signals. The radio frequency signals can be orthogonally polarized. Branch circuits in each receiver segment can provide a radio frequency signal to different mixers. The different mixers can be included in different receiver segments and receive local oscillator signals from independent local oscillators. Each receiver segment can process a different bandwidth of the radio frequency signal. Two different bandwidths of the radio frequency signal can be processed concurrently by different receiver segments.

Abstract: Provided herein are apparatus and methods for wideband receivers. In certain configurations, a radio frequency (RF) communication system includes two or more receiver slices that operate in parallel with one another to process an RF input signal. The receiver slices generate digital signals by processing different sub-bands of the RF input signal. For example, the RF communication system can include a first receiver slice that processes a first sub-band of the RF input signal and that generates a first digital signal representing the first sub-band, and a second receiver slice that processes a second sub-band of the RF input signal and generates a second digital signal representing the second sub-band. The RF communication system further includes a clock generation circuit that generates one or more clock signals to control timing of the receiver slices, and a sub-band processing circuit that processes the digital signals from the receiver slices.

Abstract: A method of operating a radio frequency transceiver may include generating, by a transmit circuit of the transceiver, in-phase (I) and quadrature (Q) analog signals based on a digital calibration signal; mixing, by the transmit circuit, the I and Q analog signals with local oscillator (LO) and phase shifted LO signals to generate upconverted I and Q signals, the LO signal having a first frequency, and combining the upconverted I and Q signals to generate a combined signal; and converting, by a receive circuit of the transceiver, a signal based on the combined signal to a received digital signal using a sampling rate at a second frequency, the second frequency being less than the first frequency, wherein the converting downconverts frequency content in the combined signal.
