Abstract |
In this paper, a fully integrated Ku-band tripler differential MMIC voltage controlled oscillator(VCO), which consists of a differential VCO core and two triplers, is developed using high linearity InGaP/GaAs HBT technology. The VCO core generates an oscillation frequency of 3.583 GHz, an output power of 3.65 dBm, and a phase noise of -96.7 dBc/Hz at 100 kHz offset with a current consumption of 30 mA at a supply voltage of 2.9 V. The tripler shows excellent side band rejection of 23 dBc at 3 V and 12 mA. The tripler differential MMIC VCO produces an oscillation frequency of 10.75 GHz, an output power of -13 dBm and a phase noise of -89.35 dBc/Hz at 100 kHz offset. |
