AN EXPERIMENTAL-STUDY ON FREQUENCY-SYNTHESIZERS USING PUSH-PUSH OSCILLATORS

This paper describes the fundamental principle of novel push-push osci llators using hairpin-shaped split-ring resonators and their applicati on to voltage controlled and injection locked oscillators for frequenc y synthesizers. The experimental results make it clear that the synthe sizer systems discussed here have the advantages of high frequency ope ration, compact size and low power consumption. Experimental work has been carried out in the L band, but these systems can be applied to mu ch higher frequencies.
