Product Details

MDU1100T Microwave Doppler Motion Detector Module - 10.587 GHz (UK)

The Microwave Solutions MDU1100T Motion Detector Module is an X-Band Microwave Transceiver that utilises the Doppler Effect to detect movement. The MDU1100T emits a microwave signal which is compared against the returned signal for frequency shift, indicating movement. This comparison generates an IF output signal that can be amplified and processed by host system circuitry.

The MDU1100T features a tuneable resonator that allows the transceiver to be tuned over a frequency range of approximately 5 MHz at room temperature. This enables the application of frequency modulation to the transceiver and makes FSK ranging possible.

This version of the MDU1100T operates at 10.587 GHz making it suitable for applications in the UK.
