    • In embodiments of variable antenna match linearity, a wireless device includes a first transceiver and a second transceiver, an antenna via which signals are received, and a linearity controller that varies a linearity of an antenna match circuit associated with the antenna. The linearity controller can determine whether a frequency of an intermodulated signal that includes transmissions from the first and second transceivers is within one of a respective receive band of the first transceiver or the second transceiver. The linearity controller can increase a linearity of the antenna match circuit to mitigate an amplitude of the intermodulated signal in the receive band.
    • 在可变天线匹配线性度的实施例中,无线设备包括第一收发器和第二收发器,接收信号的天线以及改变与天线相关联的天线匹配电路的线性度的线性控制器。 线性控制器可以确定包括来自第一和第二收发器的传输的互调信号的频率是否在第一收发器或第二收发器的相应接收频带之一内。 线性控制器可以增加天线匹配电路的线性度以减轻接收频带中的互调信号的幅度。

    • A method and system synchronizes transmission of receive data over an asynchronous digital radio frequency interface in a wireless communication device. A timing accurate strobe (TAS) re-sampler generates, using a first timing strobe synchronized to a baseband modem clock, a second timing strobe synchronized to a radio frequency integrated circuit (RFIC) clock. The TAS re-sampler forwards the second timing strobe to the RFIC to trigger a collection of data samples and initiates a count of RFIC clock cycles. The RFIC sends the data samples to a baseband First In First Out (FIFO) buffer over the asynchronous interface. In response to the count reaching a pre-determined number of RFIC clock cycles corresponding to a fixed delay, the TAS re-sampler triggers a reading of data from the FIFO buffer. The baseband modem receives data corresponding to the collection of data samples after a fixed delay from generation of the first timing strobe.
    • 方法和系统通过无线通信设备中的异步数字射频接口同步接收数据的传输。 定时精确选通(TAS)重采样器使用与基带调制解调器时钟同步的第一定时选通器产生与射频集成电路(RFIC)时钟同步的第二定时选通。 TAS重新采样器将第二个定时选通器转发到RFIC以触发数据采样的收集并启动RFIC时钟周期的计数。 RFIC通过异步接口将数据样本发送到基带先入先出(FIFO)缓冲区。 响应于计数达到对应于固定延迟的预定数量的RFIC时钟周期,TAS重新采样器触发从FIFO缓冲器读取数据。 基带调制解调器在产生第一定时选通脉冲之后的固定延迟之后接收对应于数据样本采集的数据。

    • A radio frequency (RF) communication device comprises a first signal propagating circuit and a second signal propagating circuit, which together enables simultaneous transmission. The first signal propagating circuit is configured with a first tunable notch filter within a first transmit path and the second signal propagating circuit is configured with a second tunable notch filter within a second transmit path. A controller is communicatively coupled to a respective first tuning component and second tuning component of the tunable notch filters. The controller selectively tunes at least one of the tunable notch filters during signal propagation to produce a specific combined notch filtering response that reduces a level of IMD on at least one receive carrier frequency of at least one propagating signal. Aspects of the disclosure also provide a method for making the communication device.
