A mixer circuitry comprises a mixer, a local oscillator (LO) leakage detector, a digital LO leakage cancellation controller and a DAC arrangement. The mixer is configured to mix a first LO signal having an LO frequency f.sub.LO with an intermediate frequency (IF) signal and generate an output signal, i.e. a wanted signal. The LO leakage detector measures the LO leakage at the output of the mixer in the presence of the wanted signal. Then in the digital LO leakage cancellation controller, a digital algorithm is run that automatically adjusts the LO leakage in the mixer by steering the digital-to-analog converter arrangement such that the intermediate frequency input signal level to the mixer is adjusted.

Methods and systems are disclosed for concurrent transmission or resource blocks allocated to a mobile device for transmission in uplink communication channels. In particular implementations, a mobile device may tune local oscillators and/or apply filtering of radio frequency transmission to reduce or mitigate intermodulation distortion potentially affecting one or more radio frequency receiving functions.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may tune a first voltage controlled oscillator (VCO) to an offset frequency from a particular frequency, wherein the offset frequency differs from the particular frequency by an offset, wherein the offset is based at least in part on at least one parameter, and wherein the UE is configured to operate in an at least one carrier mode associated with at least one time division duplexed carrier; and communicate, while the first VCO is tuned to the offset frequency, a communication associated with a second VCO, wherein the second is tuned to the particular frequency. Numerous other aspects are provided.

An electronic device includes a signal processor, a substrate, and a conductive housing. The signal processor includes an oscillator that outputs oscillation signal. The substrate has a ground component, the signal processor being disposed on the substrate. The conductive housing is connected to a first site of the ground component and to a second site that is different from the first site. The first site and the second site are disposed at positions where a first area of the housing that is an odd-numbered multiple of wavelength of the oscillation signal away from the first site overlaps at least part of a second area of the housing that is a multiple of wavelength of the oscillation signal away from the second site.
