    Abstract: Radar circuitry can include an isolator and a mixer. The isolator can isolate a transmission signal path and a reception signal path from each other, and generate a mixing (e.g. oscillation) signal based on a transmission signal. The isolator can be coupled to the mixer such that the drive signal drives the mixer (e.g. serves as the local oscillation signal of the mixer). The mixer mixes a received signal and the drive signal to generate a converted signal (e.g. a down-converted signal). The isolator can be a hybrid transformer or electrically balanced duplexer.

    Abstract: A transmit receive switch (TRSW) system is disclosed. The system has a transmission line, a transformer based matching network, a shunt switch, an amplifier and circuitry. The transmission line is connected to an antenna port. The transformer based matching network is connected to the transmission line and has a first coil and a second coil, wherein the second coil is connected to the transmission line. The amplifier can be configured as a shunt switch when inactive. The shunt switch, including the amplifier configured as the shunt switch, can be connected to the first coil of the transformer based matching network. The circuitry is configured to cause the shunt switch to be ON during an inactive mode and create a short across the first coil. Combined, the length of transmission line needed to complete the impedance transformation is reduced, thereby lowering the overall insertion loss of the transmit/receive switch.

    Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels. In some embodiments, a contention-based channel access procedure may be performed to attempt to gain access to both a primary channel and an auxiliary channel. A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted. During asymmetrical full-duplex operation, the primary transceiver may be configured to communicate data packets using the primary channel, and the auxiliary transceiver may be configured to communicate control packets using an auxiliary channel.

    Abstract translation: 多收发器无线通信装置的实施例和用于自适应多频带通信的方法在本文中一般地被描述。 在一些实施例中，多收发器无线通信设备可配置用于半双工操作和用于两个非干扰信道上的非对称全双工操作。 在一些实施例中，可以执行基于竞争的信道接入过程以试图获得对主信道和辅助信道的接入。 当允许访问主信道和辅助信道时，主收发机和辅助收发机可被配置用于不对称全双工操作。 其中一个收发器可以被配置为半双工操作，当仅允许访问仅一个信道时。 在非对称全双工操作期间，主收发器可以被配置为使用主信道传送数据分组，并且辅助收发机可以被配置为使用辅助信道来传送控制分组。

    Abstract: Systems, methods, and circuitries are provided for a local oscillator (LO) signal distribution. An exemplary LO distribution network includes a common LO buffer configured to buffer an LO signal, a receive (RX) LO buffer, and a transmit (TX) mixer in a cascaded arrangement. The RX LO buffer is configured to receive the LO signal and buffer the LO signal and to provide the LO signal to an RX mixer. A first LO signal line and a second LO signal line are configured to conduct the LO signal from the common LO buffer to the RX LO buffer. The RX LO buffer is coupled to the first LO signal line and the second LO signal line. The TX mixer is also coupled to the first LO signal line and the second LO signal line.
