Abstract: An aspect includes a filtering method including operating a first filter to filter a first input signal to generate a first output signal; operating a second filter to filter a second input signal to generate a second output signal; and selectively coupling at least a portion of the second filter with the first filter to filter a third input signal to generate a third output signal. Another aspect includes a filtering method including operating switching devices to configure a filter with a first set of pole(s); filtering a first input signal to generate a first output signal with the filter configured with the first set of pole(s); operating the switching devices to configure the filter with a second set of poles; and filtering a second input signal to generate a second output signal with the filter configured with the second set of poles.

Abstract: Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and circuitry for a t-switch with gate shunting. One aspect is an apparatus including a first differential switch having a control input. The apparatus further includes a second differential switch coupled to the first differential switch, the second differential switch a control input. A shunt capacitor is coupled between a first output and a second output of the first differential switch, and a first input and a second input of the second differential switch. A first shunt switch having a control input, an input, and an output has the input and the output coupled to the control input of the first differential switch. A second shunt switch having a control input, an input, and an output, has the input and the output coupled to the control input of the second differential switch.

Abstract: An aspect includes a filtering method including operating a first filter to filter a first input signal to generate a first output signal; operating a second filter to filter a second input signal to generate a second output signal; and merging at least a portion of the second filter with the first filter to filter a third input signal to generate a third output signal. Another aspect includes a filtering method including operating switching devices to configure a filter with a first set of pole(s); filtering a first input signal to generate a first output signal with the filter configured with the first set of pole(s); operating the switching devices to configure the filter with a second set of poles; and filtering a second input signal to generate a second output signal with the filter configured with the second set of poles.

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: Techniques and apparatus are described for reducing power consumption when performing wireless communications by dynamically changing the frequency of a local oscillator signal for a radio frequency (RF) downconversion circuit, based on signal conditions. An example method includes receiving an RF signal and downconverting the RF signal using an oscillating signal with a first frequency at a first time. The method also includes switching to downconverting the RF signal using the oscillating signal with a second frequency, based on a property associated with the RF signal at a second time. The second frequency is a subharmonic of the first frequency.
