摘要: 介绍了一种基于六端口的双频信号接收方法。在射频六端口网络工作的频率范围内，使用一个合适的校准方法可以同时下变频两个射频信号，这两个射频信号可以是不同调制方式、不同带宽、不同标准的射频信号。文中推导了该方法的数学模型，并通过实验仿真验证了该方法对16QAM和64QAM信号的解调性能，仿真得到的误比特率(BER)和误差矢量幅度(EVM)表明该方法具有较好的信号解调性能。与传统的双频接收机相比，六端口电路易于MMIC集成，支持的带宽更宽，没有多余的下变频支路，可以用在多种无线电应用中。
Abstract: This paper introduces a two-frequency signal receiving method based on the six-port. Using a suitable calibration method can down convert two different RF signals at the same time; these two RF signals can be with different modulation mode, different bandwidth and different standards of RF signals. This paper deduces the mathematical model of this method, and this method is verified by the performance simulation of 16QAM and 64QAM signal demodulation. The bit error rate (BER) and error vector magnitude (EVM entry) obtained from simulation show that the method has a better signal demodulation performance. Compared with the conventional dual-band receiver, six- port circuit is easy to MMIC integrated, the bandwidth is wider, there is no redundant frequency conversion, and it can be used in many radio applications.
