A 20-GHz-band injection-locked oscillator MMIC, which incorporates a novel active four-port combiner/divider and a simple feedback path, is presented. This ILO MMIC measures only 1.0/spl times/1.2 mm, operates in an injection-locked state at subharmonic factors from 1 to 1/4 without buffer amplifiers, and suppress the undesired harmonics of the injected… CONTINUE READING
