Abstract: Some embodiments of the present disclosure relate to multiband receivers that include at least one divider unit having a divisor that is other-than-two. For example, in some embodiments the divisor is an odd integer (e.g., three). Such divisors allow oscillators for respective receiver subunits in a multi-band receiver to have frequencies that are sufficiently different from one another so as to limit cross-talk interference there between, even when the receiver subunits are concurrently receiving data on adjacent channels. To facilitate this other-than-two divisor, a phase error compensation block is often used to compensate for the effects of using the other-than-two divisor.

Abstract: Some embodiments of the present disclosure relate to a feedback receiver comprising a threshold comparator configured to determine if the amplitude of a baseband signal is within a selection corridor (e.g., defined by an upper and lower threshold value). If the amplitude is within the selection corridor, a feedback receiver is configured to accumulate RF signal samples (e.g., amplitude and phase samples) over a time period. The accumulated RF signal samples, which correspond to substantially constant baseband amplitude values, are then averaged. The calculated averages are utilized for impedance measurements used tune an antenna tuner to limit impedance mismatch. By limiting RF amplitude and phase sample collection to associated baseband signals having an amplitude falling within the selection corridor, substantially equal average amplitudes and phases can be achieved over a relatively short measurement period (i.e., without the need for long measurement period).
