| Zusammenfassung: | A new directional coupler with a frequency control circuit and parallel LC resonator is presented. An exact analysis for a variable directional coupler is derived. Changing the resonance frequency of the parallel resonator for the proposed directional coupler can provide tunable frequency characteristics and a wide operating frequency range. |
