PRESSURE SENSOR ASSEMBLIES

A pressure sensor assembly includes a first receive antenna array configured to receive a first signal at a first frequency, a second receive antenna array configured to receive a second signal at a second frequency that differs from the first frequency, and a diode coupled to the first receive antenna array and the second receive antenna array. The diode is configured to receive the first signalat the first frequency and the second signal at the second frequency and output a third signal at a third frequency that is a difference between the first frequency and the second frequency. A transmit antenna array is coupled to the diode. The transmit antenna array is configured to receive the third signal at the third frequency and output the third signal at the third frequency. The invention also provides a pressure sensing method. 本发明涉及一种压力传感器组件。该压力传感器组件包括：被构造成接收处于第一频率的第一信号的第一接收天线阵列；被构造成接收处于与第一频率不同的第二频率的第二信号的第二接收天线阵列；以及耦合到第一接收天线阵列和第二接收天线阵列的二极管。二极管被构造成接收处于第一频率的第一信号和处于第二频率的第二信号，并且输出处于第三频率的第三信号，该第三频率是第一频率和第二频率之间的差。发
