Abstract :
Operation of high-power X and K. band transferred-electron oscillators (t.e.o.s) in waveguide circuits is described. An increase in c.w. efficiency from 2.5 to 3.5% by decreasing the impedance of the waveguide circuit is reported. Output powers as high as 1.0 W at 10 GHz with 2.5% efficiency and 500 mW at 20 GHz with 3% efficiency were obtained in a ridge-waveguide circuit.
