Abstract :
Having a proven beam system focused by a periodic permanent magnet structure, rf circuits to achieve 700Watts CW of power amplification at Ka-Band have been designed. These circuit designs have been further explored and correlated to TESLA-CC (US Naval Research Laboratory´s newly developed code) simulation results and to measured data.
