Amplitude and Phase Characteristics of Microwave Solid State Amplifiers for Phased Array Antenna Service
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.
