Extended Interaction Oscillator and Amplifiers (EIO/A) have proven to be reliable high power sources of millimeter waves.1 Their unique capabilities have been demonstrated in various modulator configurations. Proper selection and tailoring of the modulator will define the capability of the EIO/A to meet the requirements of the radar system. This paper describes the basic characteristics of the EIO/A, the typical modulator configurations developed to drive the EIO/A, and comparative results attained by each method.
