Abstract: A transceiver that allows dynamic high-pass filter (HPF) cut-off frequency adjustment may include a mixer circuit to mix a local oscillator (LO) signal with a receive (RX) signal received from a transmitter to generate a baseband signal. The transceiver may further include a high-pass filter (HPF) having an adjustable cut-off frequency that is used to reduce a DC offset of the baseband signal. A control circuit can dynamically control components of the HPF to set the adjustable cut-off frequency at a first frequency during a first time period and at a second frequency during a second time period.

Abstract: A wireless power transmission system may include a wireless power transmitting device such as a tablet computer and a wireless power receiving device such as a computer stylus. A wireless power transmitting capacitor electrode may be formed in the tablet computer. A wireless power receiving capacitor electrode may be formed in the computer stylus. The transmitting capacitor electrode may be driven by a drive signal having a frequency of 900 MHz or greater to produce wireless power. The wireless power may be transmitted from the transmitting capacitor electrode to the receiving capacitor electrode on the stylus via near field capacitive coupling. The transmitting and receiving capacitor electrodes may each include conductive traces on dielectric substrates. The conductive traces may follow meandering paths to maximize the possible capacitive coupling efficiency between the capacitor electrodes and thus the end-to-end charging efficiency of the wireless power transmission system.

Abstract: A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device. Once the internal amplifier has reached its maximum power, further requests for power increases from the remove device do not similarly lead to automatic power increases being delivered by a external amplifier of the host device. Rather, the host device determines the strength of the link between it and the remote device. If the signal strength is too low, it is an indication that the signal power output by the remote device may not be sufficient to maintain the link and that any further increases in signal power by the host device will have little or no effect on the link. However, if the signal strength from the remote device is sufficient, the host device determines an error rate between it and the remote device. If the error rate is sufficiently low to maintain the link, then the host device will not further increase its signal output power. However, if the error rate is too high, the host device will turn on and/or increase power from its external amplifier to boost the power of its output signal and, thus, improve the error rate between it and the remote device.

Abstract: A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device coupled via a data link. Once the internal amplifier has reached its maximum power, the host device may determine the strength of the data link between it and the remote device. If the strength is low, it is an indication that further increases in signal power by the host device may have little effect on the link. If the signal strength from the remote device is sufficient, the host device determines an error rate. If the error rate is sufficiently low, the host device will not increase its signal output power. However, if the error rate is too high, the host device may increase power from its external amplifier to improve the error rate of the data link.

A peripheral conductive member may run around the edges of the housing and may be used in forming the first and second antennas. The radio-frequency transceiver circuitry may have a transmit-receive port and a receive port. Switching circuitry may connect the first antenna to the transmit-receive port and the second antenna to the receiver port or may connect the first antenna to the receive port and the second antenna to the transmit-receive port.

Abstract: The present techniques relate to reducing interference on conducted RF links by utilizing country information to determine where an electronic device is located, and using such information to select sub-bands or channels that are not available for wireless transmission to be used for transmission of signals via the conducted RF links. Because the conducted RF links operate on frequency bands that are different from the frequency bands used for wireless communications in a given country, there is less likelihood that wireless communications will create interference in the signals being transmitted via the conducted RF links.
Abstract translation: 本技术涉及通过利用国家信息来确定电子设备所在的位置来减少对传导RF链路的干扰，并且使用这样的信息来选择不可用于无线传输的子频带或信道，以用于信号传输 传导的RF链路。 由于传导的RF链路在与给定国家中用于无线通信的频带不同的频带上操作，所以无线通信将在经由传导的RF链路传输的信号中产生干扰的可能性较小。

Abstract: A technique for reducing interference on conducted RF links involves a determination of active wireless channels in an electronic device. For example, the device can determine whether there are any active cellular, WiFi, and/or Bluetooth channels. If so, any active channels can be removed from a list of possible channels that can be used for generating the RF signals for the conducted RF link. If any idle channels remain available, one or more may be selected for use for the conducted RF link. Those idle channels having a higher offset from any active channels may be given a greater weight in the selection since they should be less likely to be subject to interference. If not, one of the least crowded active channels may be selected for use for the conducted RF link.
Abstract translation: 用于减少对传导RF链路的干扰的技术涉及确定电子设备中的主动无线信道。 例如，设备可以确定是否存在活动的蜂窝，WiFi和/或蓝牙信道。 如果是这样，可以从可用于生成用于传导RF链路的RF信号的可能信道的列表中移除任何活动信道。 如果任何空闲信道保持可用，则可以选择一个或多个用于所传送的RF链路。 那些具有比任何活动通道偏移较大的空闲信道可能在选择中给予较大的权重，因为它们应该不太可能受到干扰。 如果不是，可以选择最不拥挤的活动频道中的一个用于传导的RF链路。
