摘要： Multiple out-of-plane planar reflectors can be used to build a receive/transmit high-gain directional antenna. The driver portion and the first reflector of the antenna are formed within a metal layer of a PWB. A plurality of sets of reflector plates can be placed on the PWB, on a non-conductive low-dielectric constant material coating both opposing planar surfaces of the PWB, or on the opposing sidewalls of the product housing unit. The metal layer in the PWB is placed between the reflector plates. The plates can have either a parallel or non-parallel orientation to each another. This greatly increase the received power and thus increases the operating range of a low-power UWB system, as well as significantly improves wireless data transmission throughput. This antenna is applicable for USB communications systems.

摘要： Multistage RF transmitter and receiver circuits may use independently variable RF and IF local oscillators, allowing the RF and IF local oscillator frequencies for a given RF channel to be selected to have a large common factor with respect to the reference oscillator used by the local oscillator circuits, thus allowing the use of small divisor numbers in the local oscillator circuits and reducing phase noise. Independent high-side and low-side RF local oscillators may be provided and selectively used depending on the RF channel to be transmitted or received.

摘要： Systems and methods for canceling static and dynamic DC offsets by combining a digital DC offset correction scheme with an analog DC offset correction scheme. A feedback-based digital DC offset correction scheme provides different adjustment levels for a plurality of discrete gain states and the analog DC offset correction scheme operates in different cancellation modes dependent on a frame structure. A digital DC offset correction scheme collects DC offset control information and provides adjustment levels. In addition, a negative-feedback based switchable high pass filter has a plurality modes of operation, where one mode of operation includes an all-pass filter.
