摘要： Disclosed herein are devices and methods to reduce unwanted CIM3 emission in a wireless communication device, such that the transmit (TX) power level applied in a RU can be increased without exceeding a regulatory emission requirement. In some aspects, unwanted emission may be reduced by shifting or changing local oscillator (LO) frequencies during TX operation. Some embodiments are directed to a fast-locking PLL with adjustable bandwidth that can be controlled to increase the PLL bandwidth during the RX to TX transition to provide a fast locking to a new LO frequency. Some aspects are directed to configuring an LO frequency shift amount for different RUs when multiple RUs are allocated within a frequency band.

摘要： A switched-mode power supply (SMPS) and a method of control thereof is described, wherein the SMPS is operable to apply a spread spectrum modulation to a switching driver signal to reduce EMI in the SMPS. The SMPS is operable to perform voltage and current monitoring in parallel to the spread spectrum modulation to provide variable limit threshold detection and shutdown capabilities for circuit protection.

摘要： A receiving apparatus comprises: a plurality of tuners; and a controller that controls a frequency of a local oscillation signal from each tuner such that a frequency of a synthetic signal generated by multiplying the local oscillation signals from the plurality of tuners by each other does not fall in a frequency band of a channel selected by each tuner. Deterioration in reception quality due to the multiplication of the local oscillation signals is prevented.
