摘要： A receiver, in accordance with one embodiment of the present invention, includes a mixer, a filter, a received signal strength indicator, and a control loop. The mixer is adapted to convert the frequency of a received signal. The filter is adapted to filter out undesired noise that may be present in the output signal of the mixer. The received signal strength indicator is adapted to detect blocker (also known as jammer) signals that may be present in the output signal of the low-pass filter and generate a feedback signal in response. The control loop is adapted to vary its bandwidth in response to an output signal of the received signal strength indicator. The control loop supplies an oscillating signal to the mixer.

摘要： An on-chip antenna switching scheme for Gigahertz frequencies where for the transmission path a first on-chip switching means is coupled between an on-chip power amplifier and an antenna. In the receiving path a second on-chip switching means at an input to an on-chip low noise amplifier (LNA) connects to ground. Coupled off-chip between the first switching means and antenna and antenna and the second switching means are impedance matching means and a half and a quarter wavelength line, respectively. In transmission mode both switching means are closed, in receiving mode both switching means are open. This allows for optimal transmission of the signal in either direction.
摘要翻译：用于千兆赫兹频率的片上天线切换方案，其中对于传输路径，第一片上开关装置耦合在片上功率放大器和天线之间。在接收路径中，片上低噪声放大器（LNA）的输入处的第二片上切换装置连接到地。第一开关装置与天线和天线之间的片外耦合和第二开关装置分别是阻抗匹配装置和半和四分之一波长线。在传输模式中，两个切换装置都是关闭的，在接收模式中两个切换装置都是打开的。这允许信号在任一方向上的最佳传输。
