RADIO FREQUENCY RECEIVER WITH DUAL BAND RECEPTION AND DUAL ADC

摘要

A radio frequency receiver with dual band reception and dual analog-to-digital converters (ADCs) can be configured to operate in a single channel mode or a dual channel mode to receive a single RF input channel or two RF input channels at the same or different frequency bands. In the single channel mode, the dual ADCs can be used to improve the performance of the receiver for the single input signal or the dual ADCs can be configured for reduced power consumption. In the dual channel mode, the dual ADCs operate on the individual RF input signals to realize dual band reception. In one embodiment, the receiver is configured for asymmetric dual band reception to receive a wideband input signal on a first input signal path and a narrow band input signal on a second input signal path.
