Abstract:
A circuit for providing AM/PM modulation is described. The circuit provides two drive signals which are later combined in a constructive/destructive fashion. The circuit provides AM modulation with a drive signal having a consistent power level modulated to have varying pulse widths in order to provide variable power within each cycle.
