The DF990 sensor belongs to the DF-series K-band sensors designed specifically for long range traffic applications. With a built-in Voltage-Controlled Oscillator (VCO), it is the ideal radar frontend to provide precise speed and distance measurements via 2 analog quadrature channels. It is designed to be lightweight and has a pre-amplifier with an extended dynamic range. Typical applications include radar speed signs, traffic monitoring and sports radars.
