Abstract :
The authors describe the fundamental characteristics of compact stepped impedance hairpin resonators with parallel coupled lines, and show their application to voltage-controlled push-push oscillators for UHF band operation. The experimental push-push oscillators built using these resonators provide low phase noise and wide tuning operation.<>
