Abstract
Abstract An active semiconductor array coupled to high frequency fields supported by a symmetric passive array of radial transmission line elements serves as a high frequency transducer for amplifying the high frequency fields. The radial transmission line configuration achieves stable low-loss combining power from the individual diodes of the diode array and permits coupling of the several passive circuits to a common output with suppression of undesired oscillation modes.
