摘要： A diversity receiver includes a first receiving channel and a second receiving channel. The receiver also includes a baseband processor that computes a difference between the received signal strengths of the signals received from the first and second channels, wherein the processor disables the signal received from the second channel if the difference is greater than a first threshold value and a BER associated with the second receiving channel is greater than a BER threshold value, and disables the signal received from the first channel if the difference is less than the negative first threshold value and the bit error rate (BER) associated with the first channel is greater than the BER threshold value. The receiver further includes a bypass circuit coupled to an input of an amplifier and a RSSI circuit that provides a conduction path between the input and a ground when the RSSI circuit detects a blocker signal.

摘要： Methods and apparatus for calibrating In-phase and Quadrature imbalance within a receiver are described. A calibration process can inject a calibration tone to an RF or IF portion of a receiver. The receiver can frequency translate the tone to distinct I and Q calibration signals. The receiver upconverts the I and Q calibration signals to complementary sidebands or images using distinct and substantially matched upconverters. The complementary sidebands are mixed together to generate an error signal. The receiver determines a phase and amplitude correction based on the error signal.

摘要： A receiver configured to selectively receive an RF signal from an operating band having a plurality of RF channels. The receiver is configured to upconvert the desired RF channel to an intermediate frequency (IF) greater than the RF channel frequencies. The upconverted RF channel is downconverted to baseband or a low IF. The receiver can perform channel selection by filtering the baseband or low IF signal. The baseband or low IF signal can be upconverted to a programmable output IF.
