Abstract :
The amplitude and phase of the fundamental and its harmonics at the output of various microwave solid state amplifiers have been measured as a function of load mismatch. Results are obtained for load impedances that lie on a selected series of VSWR circles on a Smith Chart and are presented as equi-power and equi-phase contours in the overall region of load variation. L-and S-band bipolar transistor modules designed for phased array antenna service and various experimental S-band TRAPATT amplifiers have been evaluated. The results are relevant to regulations on permissible radar emissions being drafted in the U.S.A.
