Abstract

PURPOSE:To increase the Q0 of a resonator and increase the CN ratio without increasing the size of the shape by coupling an active element which has negative resistance when a resonator is in a resonance state with the resonator electromagnetically. CONSTITUTION:The active element 6 which has the negative resistance when the resonator 1 is in the resonance state is coupled with the resonator 1 electromagnetically. Namely, the FET 2 of the resonator 1 performs self-excited oscillating operation to oscillate at the resonance frequency of the resonator 1, but the amplifier 8 consisting of the active element has the negative resistance at this time and energy is supplied to the resonator 1. Consequently, the loss of the resonator 1 is canceled and the loss resistance of the whole resonator decreases to obtain Q0 equivalently.
