Datasheet: Planar MDU1020 - Fixed Freq.

The MDU (Motion Detector Unit) is an X-Band microwave transceiver that utilizes the Doppler shift phenomenon to "sense" motion. The unit is available with either of two physically interchangeable forms; A rugged cast metal housing or a lightweight plastic housing.

The circuit features a dielectric resonator stabilized 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.
