Abstract :
A 26.4 GHz phase locked oscillator (PLO) for communication satellite is fabricated. The PLO consists of two parts - Fundamental Frequency Generation Module (FFGM) and Frequency Multiplication Part (FMP). FFGM generate highly stable 8.8 GHz oscillating signal using VCDRO and SPD. Frequency tripling process occurred in the FMP. MMIC tripler and amplifier are used for the reduction of the size and mass of FMP. The phase noise of 26.4 GHz PLO is exhibited as -96 dBc/Hz at 10 kHz offset frequency and -105 dBc/Hz at 100 kHz offset frequency, respectively, with the output power of over 11 dBm.
