摘要： A communication channel has a highly linear switched current mixer that incorporates passive filtering (e.g., low pass, notch) for improved transmitting (Tx) and receiving (Rx) with adding external filtering components. A high IIP2 (input referenced second order intercept point) of the receiver at the Tx offset is essential to avoid corrupting the system's sensitivity performance, and a high triple beat (TB) is required to avoid sensitivity degradation due to transmitter leakage. Thanks to the embedded filtering in the mixer and the active post-distortion (APD) method in a low noise amplifier (LNA), the required high linearity is achieved with low noise figure and power consumption, overcoming transmitter power leakage without the use of a SAW (surface acoustic wave) filter.
摘要翻译：通信通道具有高度线性的开关电流混频器，其结合无源滤波（例如，低通，陷波），用于通过添加外部滤波组件来改进发射（Tx）和接收（Rx）。接收机在Tx偏移处的高IIP2（输入参考二阶截取点）对于避免破坏系统的灵敏度性能至关重要，并且需要高三重（TB）以避免由于发射机泄漏引起的灵敏度劣化。由于混频器中的嵌入式滤波器和低噪声放大器（LNA）中的主动后失真（APD）方法，所需的高线性度可通过低噪声系数和功耗实现，克服发射机功率泄漏而不使用 SAW（表面声波）滤波器。
