Abstract: This disclosure provides systems, methods, and devices for wireless communications that support enhanced phase calibration operations. In a first aspect, an apparatus for wireless communications includes a processing system. The processing system is configured to cause the wireless communication device to: receive a reference signal at a respective input of a plurality of receive chains; process, by each receive chain, the reference signal to generate a respective output signal; determine, for each receive chain, a phase alignment difference between the respective output signal of the receive chain and a reference output signal of a reference receive chain of the plurality of receive chains; and adjust a phase alignment of a divider of at least one receive chain of the plurality of receive chains based on the determined phase alignment difference for the at least one receive chain. Other aspects and features are also claimed and described.

Abstract: Attenuators are disclosed according to various aspects. In some aspects, an attenuator includes resistors coupled along a resistive path, wherein a first one of the resistors is coupled to an input of the attenuator, and shunt circuits, wherein each one of the shunt circuits is coupled between a respective node on the resistive path and an output of the attenuator. In other aspects, an attenuator includes routing circuits coupled in parallel between an input of the attenuator and an output of the attenuator, wherein each one of the routing circuits includes a respective series resistor and a respective series switch coupled in series between the input of the attenuator and the output of the attenuator, and a respective switchable resistor circuit coupled to a respective node between the respective series resistor and the respective series switch, wherein resistances of the series resistors of the routing circuits are binary weighted.

Abstract: This disclosure provides systems, methods, and devices for wireless communications that support downconversion of signals with improved harmonic rejection. In a first aspect, an apparatus includes a first plurality of mixers with each mixer coupled to two oscillating signals that are 180 degrees apart in phase; a second plurality of mixers with each mixer coupled to two oscillating signals that are 180 degrees apart in phase, wherein a combined load of the first plurality of mixers and the second plurality of mixers on the plurality of oscillating signals is symmetric as to each oscillating signal of the plurality of oscillating signals; and a shared capacitor coupling the RF input to the first plurality of mixers and the second plurality of mixers. Other aspects and features are also claimed and described.
