Abstract: Certain aspects of the present disclosure generally relate to techniques and apparatus for operating a wireless receiver of the apparatus in a high linearity mode. An example method includes operating the apparatus in a first mode with transmission of a plurality of transmit signals. The method also includes attenuating a received signal via an attenuator while operating the apparatus in the first mode. The method further includes amplifying the attenuated signal with an amplifier while operating the apparatus in the first mode. For certain aspects, the method further involves operating the apparatus in a second mode, bypassing the attenuator while operating the apparatus in the second mode, and amplifying the received signal with the amplifier while operating the apparatus in the second mode.

Abstract: This disclosure provides systems, methods, and devices for wireless communications that support dodging out-of-band (OOB) jammers. In a first aspect, a apparatus for wireless communications, such as a wireless transceiver, includes a first radio frequency (RF) processing path for processing a first RF signal, the first RF processing path comprising a first analog-digital converter (ADC) configured to sample the first RF signal based on a first clock signal; and a second RF processing path for processing a second RF signal, the second RF signal being a spatially-diverse representation of the first RF signal, and the second RF processing path comprising a second analog-digital converter (ADC) configured to sample the second RF signal based on a second clock signal, wherein a first clock frequency of the first clock signal is different from a second clock frequency of the second clock signal. Other aspects and features are also claimed and described.
