Abstract :
This paper presents a 60 GHz highly stabilized frequency source, which is composed of a 30 GHz DRO and a doubler based on 0.15 /spl mu/m gate AlGaAs/InGaAs HJFET MMIC technologies. The 30 GHz DRO exhibited low phase noise of -102 dBc/Hz at 100 kHz off-carrier with the maximum output power of 7.7 dBm. The 30-to-60 GHz doubler showed high conversion gain of -1.5 dB at the input power of 7 dBm. For the 60 GHz frequency source, markedly low phase noise of -93 dBc/Hz at 100 kHz off-carrier and better than 1.9 ppm/C frequency stability has been achieved.<>
