Abstract :
A new oscillator-combiner using two tubular dieIectrlc resonators, coupled to N transistors, M presented. An equivalent "TE" representation having N branches is introduced allowing to derive easily the oscillation-condition . Experimental results obtained with three transistors have given an oscillator with 225 mW output power at 11 GHz without spurious modes. A combiner efficiency of 75% has been measured resulting in an overall oscillator efficiency of 15%.
