  Abstract

In the thesis, For improving the Stability of VCHRO(Voltage Controlled Hair-pin Resonator Oscillator) the new structure using the parallel feedback of the second harmonic is proposed for self-phase locking effect. This module is composed of wilkinson divider, frequency doubler, directional coupler, and bandpass filter using a hair-pin resonator, which are integrated into miniaturized hybrid circuit. The module exhibits output power of 2.5
dBm at 19.5 GHz, -29.83 dBc fundamental frequency suppression and -76.52 dBc/Hz phase noise at 10 kHz offset frequency from carrier of center frequency 19.5 GHz.
