A 13 GHz phase-locked loop development for micro- and millimeter wave applications

A 13 GHz Phase-Locked Loop (PLL) employing a parametric divider is being developed for volume production of microwave and millimeter wave applications. This PLL is realized using a mixed technology of pHEMT MMICs and SMT components to insure a cost effective, microwave multi-chip assembly solution. The fundamental PLL frequency of 13 GHz can be used as a very stable oscillator source for a number of applications, including point-to-point systems, 38 GHz radio band, 65 GHz broadband network and 77 GHz automotive applications by means of successive multipliers.
