RADAR SENSOR HAVING THE MULTI-STAGE VOLTAGE CONTROLLED OSCILLATOR OF THE VOLTAGE REQUIRED FROM THE ACTIVE CIRCUIT ELEMENT AND THE SINGLE BIAS CIRCUIT SUPPLYING THE CURRENT AND AMPLIFIER

摘要

PURPOSE: The radar sensor having the multi-stage voltage controlled oscillator and amplifier of the single bias circuit has the simple circuit.;CONSTITUTION: The microwave module(100) changes the micro wave signal into the radio frequency signal. The RF module(200) changes the radio frequency signal into the intermediate frequency signal. The demodulator(301) demodulates the intermediate frequency signal. The signal processing control part(302) is input the signal demodulated with demodulator.;COPYRIGHT KIPO 2011
