“…While SiGe-MMIC oscillators on high resistivity substrates have been presented up to 47GHz [5] or hybrid push-push oscillators with SiGe-transistors up to 57GHz [7], VCOs and Oscillators on low resistivity substrate and realized in a production line process have recently been presented in the 20GHz range and beyond [8,9]. So this oscillator underlines the performance of an available SiGe-process for the 20GHz range although the used production line has been intended for the mass market at 2GHz.…”

“…This substrate is widely used because it is compatible with CMOS-technology and therefore very cheap. It is not common to use low resistivity substrates in distributed designs [5] because of the increase in loss.…”

“…For the characterization of components involved, the six-port technique [2,3] can be used as an alternative to the expensive down-converter systems used in commercial network analyzers. In this case, the complex reflection coefficient is deduced from power readings.…”

“…Excellent results have been reported already on SiGe HBT SIMMWIC oscillators concerning maximum operation frequency [2]. In this paper, results are shown on a low noise coplanar 24 GHz SiGe HBT LC oscillator, a coplanar 27 GHz SiGe HBT voltage controlled oscillator (VCO), and a low phase noise microstrip 27 GHz SiGe HBT VCO with a recently developed MST technology [3].…”
