Abstract: A dual frequency synthesizer architecture for a wireless device operating in a time division duplex (TDD) mode is disclosed. In an exemplary design, the wireless device includes first and second frequency synthesizers. The first frequency synthesizer generates a first oscillator signal used to generate a first/receive local oscillator (LO) signal at an LO frequency for the receiver. The second frequency synthesizer generates a second oscillator signal used to generate a second/transmit LO signal at the same LO frequency for the transmitter. The two frequency synthesizers generate their oscillator signals to obtain receive and transmit LO signals at the same LO frequency when the wireless device operates in the TDD mode.

Abstract: An apparatus for reducing spurs is described. The apparatus includes a coarse digital to analog converter (DAC). The apparatus also includes a correction term generator. The correction term generator generates a correction term. The correction term has an amplitude within a dynamic range of the coarse digital to analog converter (DAC). The apparatus also includes a baseband filter. The correction term is selected such that the baseband filter reduces the correction term to an amplitude approximating that of a spur in a transmit signal. The correction term is used to reduce a spur.

Abstract: Certain aspects of the present disclosure generally relate to jamming detection for radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first counter configured to count a number of times that a power of a reception signal exceeds a first threshold. The apparatus also includes a second counter configured to count a number of measurements of the power of the reception signal. The apparatus further includes control logic having a first input coupled to an output of the first counter and having a second input coupled to an output of the second counter. The control logic is configured to determine an amount of jamming over a measurement window based on the number of times that the power of the reception signal exceeds the first threshold and on the number of measurements.

Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.
