Abstract

PURPOSE:To reduce the degree of deterioration of the noise property caused by the line loss of the secondary resonator, by increasing the internal impedance of the port of the circulator which is connected to the signal secondary resonance circuit. CONSTITUTION:The 1/4-wavelength lines 5 and 6 form both the double resonating secondary resonator and the impedance transformer to be then connected to circulator 7. And if the internal impedance is set at Z0, Z0 and Z3 for the port to which the input, the output and the signal secondary resonance circuit of circulator 7 are connected each, Z3 is set in order to satisfy Z3>Z0. In such way, the property impedance can be increased for lines 5 and 6, and accordingly the degree of deterioration can be reduced for the noise property due to the line loss of the secondary resonator.
