The Microw*e Solutions MDU1100T Motion Detector Unit is an X-Band microw*e transceiver that utilises the Doppler shift phenomenon to "sense" motion. The unit, contained in a lightweight plastic housing, features an electronically tuneable dielectric resonator stabilised FET oscillator, which provides stable operation over a broad temperature range in either CW or low duty cycle pulse mode and a balanced mixer for enhanced sensitivity and reliability. 微波探测模块 MDU1100T 是一个X波段微波发射和接收一体化模块,它利用多普勒原理来探测移动物体。
