  Abstract

In this paper, we design and fabricate a VCO(Voltage Controlled Oscillator) for radar detector of X/K/Ka band using frequency multiplier. The existing VCO operated in radar detector have many problems such as narrow bandwidth, slow frequency variable rate, unstable of production due to high frequency. So we design and fabricate a VCO improved such problems using frequency multiplier. As a result of measure, investigated frequency multiple VCO show its output power 3.64 dBm at multiplied operating frequency 11.27 GHz and have wide frequency tuning range of 660 MHz by controlled voltage 0V to 4.50 V applied diode. And also its phase noise is -104.0 dBc at 1 MHz offset frequency so we obtain suitable performance for commercial use.
