Abstract

The global stability of a broadband MMIC frequency divider in the millimetric range has been analyzed by determining its bifurcation loci on a two-parameter plane. Some important characteristic to be satisfied by broadband designs are provided by these loci. The circuit bias range for operation as harmonic injection divider is also obtained by means of a very simple new approach. The new algorithm allows an easy selection of any bifurcation parameter and it is short time consuming. An excellent agreement has been obtained between simulation and experimental results.
