2.45GHz Doppler Directional Sensor is designed for motion/speed/ directional detection application where its sensitivity is very important.

The sensor is constructed with a high performance circular polarized microstrip antenna, T/R diplexer, a balanced mixer (I/Q demodulator for dual channel I/Q signals) and a high performance oscillator with a PLL circuit. The excellent frequency stability of a PLL oscillator enhances Doppler detection at low IF frequency and circular polarization waveform improves reception ability for various Radar targets.

The dual channel I/Q signal provides target moving direction (approaching or receding) information of the target while detecting speed.​
