Abstract

PURPOSE:To reduce the loss of solid-state resonator and to increase the selectivity, by connecting a resonance circuit the resonant frequency of which is selected within the pass band of a solid-state resonator, between the input and output terminals of the solid-state resonator, in the amplifier with frequency selectivity having the solid-state resonator. CONSTITUTION:A series resonance circuit consisting of a coil 100 and a capacitor 101 is inserted between the input and output terminals of a solid-state resonator. When the resonance frequency of this circuit is set around the center frequency within the pass band of the solid-state resonator 10, the signal within the pass band flows via the coil 100 and the capacitor 101 to compensate the insertion loss of the resonator 10 without deteriorating the filter characteristics. Thus, the loss of the solid-state resonator is reduced and the selectivity is increased.
