摘要： Systems, apparatus and methods in a mobile device to multiplex two global navigation satellite system (GNSS) signals on a single hardware receiver chain are presented. The GNSS signals may come from a common GNSS system on two bands of two different GNSS systems overlapping on a common band. A duty cycle of the GNSS signals may be based on a harmonic being within one of the first band and the second band. The duty cycle may be based on signal quality, such as indicating a jammed or non jammed signal. The duty cycle may be of unequal proportions and less than 100% such that the receiver chain is idle for a percentage of time.

摘要： Methods and circuits can down convert at least a first RF signal on a first path in a first frequency band to provide a first IF signal. A second RF signal on second path in a second frequency band can be down converted to provide a second IF signal. The first IF signal and the second IF signal are interspersed in the frequency domain, and the first frequency band is different from the second frequency band. A combiner can combine at least part of the first IF signal and the second IF signal to provide a combined signal on an output signal path for reception by a digital processing circuit. The first IF signal or second IF signal can be a Zero IF (ZIF), very low IF (VLIF), or Low IF (LIF) signal.

摘要： The present disclosure includes switching resonant filter circuits and methods. In one embodiment, a circuit includes a plurality of resonant switching circuits arranged in a three (3) or four (4) element PI network. In one embodiment, an undesired signal frequency is applied to two resonant switching circuits and a carrier frequency of an RF signal is applied to the other two resonant switching networks so that the network attenuates the undesired signal frequency and passes the carrier frequency. In another embodiment, the resonant switching circuits are configurable to shift a peak impedance so that undesired signals may be attenuated.

摘要： Certain aspects of the present disclosure provide methods and apparatus for performing quadrature combining and adjusting. One example circuit may include first through fourth mixing circuits. The first mixing circuit may multiply a radio frequency signal with a first local oscillating signal to generate a first frequency converted signal. The second mixing circuit may multiply a radio frequency (RF) signal with a second local oscillating signal, which may be about 90° out of phase with the first local oscillating signal, to generate a second frequency converted signal. The third and fourth mixing circuits may multiply the RF signal with the second and first signals, respectively, to generate third and fourth frequency converted signals, respectively. A first combining circuit may combine the first and third frequency converted signals, and a second combining circuit may combine the second and fourth frequency converted signals.
